The devices can control signals from DC to 3 GHz and have been optimized to provide extremely high isolation with minimal insertion loss in medium and low power applications. On chip circuitry allows positive voltage control operation at very low DC currents with control inputs compatible with CMOS and most TTL logic families. RF1 and RF2 are reflective opens when “OFF”.

Set logic gate and switch Vdd = +3V to +5V and use HCT series logic to provide a TTL driver interface. 2. Control inputs A/B can be driven directly with CMOS logic (HC) with Vdd of 3 to 7 Volts applied to the CMOS logic gates. 3. DC Blocking capacitors are required for each RF port as shown. Capacitor value determines lowest frequency of operation. 4. Highest RF signal power capability is achieved with Control set to 0/+7V.
