PIN Diode RF Switches Feature 50Ω Reflective Designs

Pasternack’s latest line of SPDT, high-power PIN diode RF switches target transmit and receive signal routing applications. With seven unique models. They are said to be desirable for connecting from an antenna to a receiver or for a transmitter with frequent change overs. The switches provide input CW power handling (hot switching) capability up to 150W, isolation levels up to 75 dB typical, and frequency ranges from 20 MHz up to 2.7 GHz.


Models are all 50Ω designs with integrated TTL logic circuitry. Typical performance includes < 0.4 dB insertion loss, up to 75 dB of isolation, maximum switching speeds as low as 150 ns, and some models specify maximum peak power levels up to 500W. Bias voltage requires either a dual bias of +5 and +15 Vdc or a single bias of +5 Vdc.  All models have an EAR99 export classification.

New VNA technologies enable mmWave broadband testing to 220 GHz, helping researchers and engineers to overcome test challenges and simplify mmWave testing.

Application development in the mmWave frequencies is growing. Broadband testing over hundreds of GHz of bandwidth is subject to repeatability/accuracy deficits, and engineers demand solutions to help overcome challenges and simplify mmWave testing.


With operating temperatures from -40°C to +85°C, the switches are available in rugged and compact packages that support SMA female connectors. Also, some models are compliant to MIL-STD-202 environmental test conditions. For more deeper insights, checkout some PIN diode RF switch datasheets and/or call 949-261-1920.
