New electromechanical switches designed for high reliability with guaranteed low insertion loss

A new series of low insertion loss repeatability electromechanical switches has been released by Pasternack. Typical applications for these switches include test instrumentation, electronic warfare, electronic countermeasures, microwave radio, VSWT, radar, space systems and research and development. The company’s 12 new models of electromechanical switches cover broadband frequencies from DC to 40GHz. They exhibit very low insertion loss repeatability with guaranteed levels of 0.03dB to 0.05dB over five to 10 million switching cycles depending on the model. The switches are offered in three configurations: SPDT, SP4T and SP6T. They are designed with latching actuators and desirable features that include indicators, self-cut-off, TTL and 50Ohm terminations. Impressive performance includes low insertion loss of 0.3dB with high Isolation of 100dB typical, and input power ratings of up to 70W CW and up to 1W for hot switching applications. These rugged and compact coaxial package assemblies are RoHS and REACH compliant, shielded for EMI/RFI suppression and magnetic fields. They are highly reliable and guaranteed to meet a series of MIL-STD-202 environmental test conditions that includes exposure to temperature cycle, humidity, altitude, vibration and shock. Depending on the model and frequency, these electromechanical switches are available with SMA or 2.92mm connectors, some models support ribbon cable assemblies for DC, indicator, and TTL logic controls. All models are export rated as EAR99. “Our new high-reliability electromechanical switches boast impressive insertion loss repeatability performance and a list of features that designers will find extremely useful. All twelve designs are available off-the-shelf with same day shipping,” said Tim Galla, product manager at Pasternack.
