New line of PIN diode RF switches

Jon Lawson

Pasternack has unveiled a new line of SPDT high-power PIN diode RF switches for transmit and receive signal routing applications. Typical uses can involve radar systems, EW applications, base station infrastructure, repeaters, military/microwave radios, public safety/land mobile radios, UHF/VHF radios and test and measurement applications.

The new line of switches consists of 7 different models. They are also for connecting from an antenna to a receiver or for a transmitter with frequent change overs. They provide input CW power handling (hot switching) capability up to 150 Watts, isolation levels up to 75 dB typical and frequency coverage ranges from 20 MHz up to 2700 MHz.

These models are all 50 Ohm designs with integrated TTL logic circuitry. Typical performance includes <0.4 dB insertion loss, up to 75 dB of isolation, maximum switching speeds of 150 nanoseconds and some models specify maximum peak power levels up to 500 watts. 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. The operational temperatures are -40°C to +85°C and they support SMA female connectors, while some models are compliant to MIL-STD-202 environmental test conditions.
