Notes:

1. Control Inputs A and B can be driven directly with CMOS logic (HC) with V of 3 to 8 Volts applied to the CMOS logic

gates and to pin 4 of the RF switch.

2. Set V to 5 Volts and use HCT series logic to provide a TTL driver interface.

3. Highest RF signal power capability is achieved with V set to +10V. However, the switch will operate properly (but at lower

RF power capability) at bias voltages down to +3V.

4. RF ByPass: Do not use RF bypass capacitors on Vdd, A or B ports. Resistors R1, R2, R3 = 100 Ohms should be

placed close to the Vdd, A and B ports. Use resistor size 0402 to minimize parasitic inductances and capacitances.

5. DC Blocking capacitors are not required for each RF port.

6. Evaluation PCB available.
