RF, microwave and millimetre wave product provider, Pasternack, has unveiled a new line of SPDT high power PIN diode RF switches that offer desirable performance for transmit and receive signal routing applications. 

Typical applications can involve use in radar systems, EW applications, base station infrastructure, repeaters, military/microwave radios, public safety/land mobile radios, UHF/VHF radios, and test and measurement applications.

Pasternack’s new line of SPDT high-power PIN diode switches consists of seven different models that offer excellent power handling and isolation with broadband performance and fast switching speed. Suited for transmit and receive applications, these solid state PIN diode switches are good 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 150W, high isolation levels up to 75dB typical and frequency coverage ranges from 20 to 2,700MHz.

These PIN diode switch models are all 50Ohm designs with integrated TTL logic circuitry. Typical performance includes less than 0.4dB insertion loss, up to 75dB of isolation, maximum switching speeds as low as 150ns and some models specify maximum peak power levels up to 500W.

Bias voltage requires either a dual bias of +5 and +15Vdc or a single bias of +5Vdc. All models have an EAR99 export classification. These PIN diode RF Switches are highly reliable with operational temperatures as wide as -40 to +85°C and are available in rugged and compact packages that support SMA female connectors, some models are compliant to MIL-STD-202 environmental test conditions.

Tim Galla, Product Manager, stated: “Pasternack’s new series of high-power PIN diode RF switches offer impressive input power handling and isolation with broadband performance and fast switching speed. Designers can select from seven different models with frequencies that range from 20 MHz up to 2700 MHz for applications that may involve radar, EW, military and commercial radios, and test and measurement. All models are readily available for urgent demands with no minimum order quantity required.”

Pasternack’s new SPDT high power PIN diode RF switches are in stock and ready for immediate shipment with no minimum order quantity.
