Quick Connections eliminate the time consuming tightening, torquing and loosening of connectors. Quick Connections are needed during testing or in applications, where limited space requirements make tightening and torquing of a coupling nut difficult or impossible. Quick Connections cover eight connector series.
Six of those nine connector series were designed by Spectrum Elektrotechnik GmbH:
Push-On connectors of types 7/16, N, TNC and SMA slide directly onto any female connector of the same series, allowing quick and easy connection and disconnection, guaranteeing repeatable performance, reduced test time and long life, operating over the full frequency range of the particular connector series with low insertion loss and excellent return loss. The connector series of types BMA, SBX, SBY and SMP were developed for a wide range of microwave interconnect problems, mate applications for modularized packages, racks and panels and dense packaging. The series SBX and SBY were developed by Spectrum Elektrotechnik GmbH for high power interconnecting modules, while BMA and SMP are used for lower power applications, SMP especially for dense packaging.

PUSH-ON connectors do not use threaded coupling nuts, they are mated by just sliding together, allowing quick and easy connection and disconnection, guaranteeing repeatable performance, reduced test times and longevity. PUSH-ONs are designed with an automatic locking mechanism, and are also available with slotted beryllium copper outer conductor only, providing the necessary insertion and withdrawal force. PUSH-ONs can be purchased with float mount, and are suited then for axial and radial misalignment. The misalignment nature is obtained by a spring mechanism which separates the connector interface from the flange housing and allows it to float for blind mating purposes. PUSH-ON connectors can be divided into two groups:
PUSH-ON CONNECTORS MATING WITH REGULAR FEMALE CONNECTORS
PUSH-ON CONNECTOR SERIES BY DESIGN
Male connectors of types 7/16, N, TNC and SMA are designed with threaded coupling nuts for safe attachment. Coupling these connectors means threading, tightening and torquing, then loosening and unthreading again. In various applications, e.g. during repetitive testing, the process for connecting and disconnecting may be more time consuming than the test cycle itself, especially when only fast go / no go tests are performed. Occasionally, limited space requirements make tightening and torquing of coupling nuts of regular connectors difficult, if not impossible.
To eliminate the time consuming tightening, torquing and loosening of regular connectors, Spectrum Elektrotechnik GmbH developed the push-on connectors, push-on connector savers and push-on adapters. The push-on connector is a male connector and does not use a threaded coupling nut. It slides directly onto any female connector of the same series, allowing quick and easy connection and disconnection, guaranteeing repeatable performance, reduced test times and long life, operating over the full frequency range of the particular connector series with low insertion loss and excellent return loss. Push-ons were designed for series 7/16, N, TNC and SMA, and in different configurations, including full locking, locking with non-locking rear nut, and non-locking.
The coupling nut of the push-on, the lock nut, incorporates an intelligent mechanism, developed by Spectrum Elektrotechnik GmbH. Easily the push-on slides onto any female connector of the same connector series, and locks safely, when released. To disconnect simply push the lock nut forward again and keep in that position until the push-on connector is removed. There are applications where longer connection is needed and where the connector must remain locked firmly. In such instances it must be assured that the push-on cannot be disconnected, not even by mistake. For that purpose a threaded rear nut is employed. With the rear nut engaged the connector cannot be pulled off, not even by mistake (Exception: no full locking version available in SMA.)
The push-on connector operates exactly like the full locking version, with the exception that the rear nut cannot be engaged.
The non-locking push-on connectors are recommended for short term testing, testing that usually takes only seconds. The nonlocking push-on connector does not employ a lock nut, therefore does not grip onto the thread of the mating female connector. The outer conductor is slotted and made from beryllium copper, heat treated. Its insertion/withdrawal force keeps the connector in place. However, cables, especially of bigger dimensions, may pull off the push-on connector when there is no guiding and securing hand. These non-locking push-on connectors should only be used for short term testing with a guiding hand on the connector for safe connection.
were developed for attachment to cable assemblies which are terminated with regular connectors. The connector saver, or adapter is supplied with a standard connector on one side, and a push-on connector at the other end. The standard connector end engages with the standard connector of opposite sex at the cable assembly. The push-on end slides directly onto any standard female of the same sex configuration. Cable assemblies are modified in seconds, changed from a standard product to a state-of-the-art push-on assembly. Some of these push-on connector savers and adapters are also available with float mount, and are suited for axial and radial misalignment. The misalignment nature of the adapter is obtained by a spring mechanism which separates the connector interface from the flange housing and allows it to float, as needed for blind mating purposes. Push-on connector savers and adapters are available within and between the series 7/16, N, TNC and SMA. They are normally supplied in full locking configuration, locking with nonlocking rear nut and non-locking. (Exception: no full locking version available in SMA.)
Several connector series, such as BMA, SBX, SBY and SMP were developed for a wide variety of microwave interconnect problems, mate applications for modularized packages, racks and panels and dense packaging. The connector series, depending on size and design are used for low, moderate and high power applications. They are designed for multiple interconnects, maintaining reliable performance and long life.
is used for lower and moderate power microwave interconnect applications, mating solutions for modular packaging, interconnecting racks and panels. The BMA float mount female connectors are suited for axial and radial misalignment. The misalignment nature of the connector is obtained by a spring mechanism which separates the connector interface from the flange housing and allows it to float. BMA connectors are available for semi-rigid cables and flexible cables as well.
connector was developed in 1993 for interconnecting high power microwave modules, using direct mount or floating rear mount, and is available as stripline connector, and as cable connector for certain standard semi-rigid cables and flexible cables as well. It operate up to 8.0 GHz. The connector is usually integrated into the housing of the component, therefore the connection normally cannot been seen from the outside. The SBX is specifically used for packaging and interconnecting those high power microwave modules, drawers and racks in state-of-the-art systems that do not allow longer system down time. Replacement of faulty high power microwave modules using the SBX can happen within seconds. The SBX float mount connectors are ideally suited for axial and radial misalignment. They employ a spring mechanism that separates the connector interface from the flange housing and allows the floating.
connector was developed in 1993 for the same program the SBX was needed and also used for interconnecting modules operating at high microwave power and is normally integrated into the housing of the component. The SBY connector is very similar to the SBX, the major difference is its smaller size and slightly different mechanical configuration. By design and due to the smaller physical dimensions it takes less power, but therefore operates to higher frequencies, namely 12.0 GHz.
is a 2.4 mm connector, using solid dielectric interface. The connector is extremely small and therefore allows high density packaging. It was originally designed to permit the female connector to incline freely in direction while the mechanical and electrical connection remains maintained. The male connector is available in smooth bore for easy connection and disconnection, with limited detent, characterized by a certain insertion and withdrawal force, and with full detent, needing high insertion force and a substantial withdrawal force, usually requiring a tool for disconnection. The full detendet SMP connection is suitable for mobile applications, extreme shock and vibration requirements. SMP connectors are offered for applications to 18.0 GHz and 26.5 GHz, precision designs are even operating to 40.0 GHz. Spectrum´s SMP connectors are meeting interface dimensions to DESC specifications 94007 and 94008. Spectrum Elektrotechnik GmbH has developed SMP test connectors as well, and designed and manufactures SMP calibration kits. Spectrum´s SMP test connectors and calibration components are supplied with an additional thread that can be employed to ensure perfect and repeatable mating during calibration.
