Set logic gate and switch Vdd = +3V to +5V and use HCT series logic to provide a TTL driver Control inputs A/B can be driven directly with CMOS logic (HC) with Vdd of 3 to 7 Volts applied to the CMOS logic DC Blocking capacitors are required for each RF port as shown.

7 Capacitor value determines lowest frequency of Highest RF signal power capability is achieved with Control set to 0/+ Circuit BoardThe circuit board used in the final application should be generated with proper RF circuit design techniques. Signal lines at the RF port should have 50 Ohm impedance and the package ground leads should be connected directly to the ground plane similar to that shown above.
