Electromechanical Switches Live Long, Lose Little

Pasternack latest electromechanical switches exhibit low insertion loss repeatability over millions of switching cycles in applications that include test instrumentation, electronic warfare, electronic countermeasures, microwave radio, VSWT, radar, space systems, and R&D.


The series consists of 12 models covering broadband frequencies from dc to 40 GHz. They exhibit very low insertion loss repeatability with guaranteed levels of 0.03 to 0.05 dB over five to 10 million switching cycles depending on the model. The switches come in three configurations: single-pole double-throw (SPDT), single-pole four-throw (SP4T), and single-pole six-throw (SP6T). They include latching actuators and feature indicators, self-cut-off, TTL and 50Ω terminations. Specs include an insertion loss of 0.3 dB, isolation of 100 dB typical, and input power ratings up to 70W CW and up to 1W for hot switching applications.


The components’ coaxial package assemblies are RoHS and REACH compliant, shielded for EMI/RFI suppression and magnetic fields, 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, they are available with SMA or 2.92-mm connectors. Some models support ribbon cable assemblies for dc, indicator, and TTL logic controls. All models are export rated as EAR99.
