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, electronic warfare applications, base station infrastructure, repeaters, military/microwave radios, public safety/land mobile radios, UHF/VHF radios, and test and measurement applications.
The range consists of seven different models that offer excellent power handling and isolation with broadband performance and fast switching speed. Ideal for transmit and receive applications, these solid state PIN diode switches are suitable for connecting from an antenna to a receiver or for a transmitter with frequent changeovers. They provide input CW power handling (hot switching) capability up to 150 W, high isolation levels up to 75 dB typical and frequency coverage ranges from 20 MHz up to 2700 MHz.
These models are all 50 Ω 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 nanoseconds and some models specify maximum peak power levels up to 500 W. Bias voltage requires either a dual bias of +5 and +15 V d.c. or a single bias of +5 V d.c.
The switches are highly reliable with operational temperatures as wide as -40°C 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.
