Typical Application Circuit

HMC545 / 545E

GaAs MMIC SPDT

SWITCH, DC - 3 GHz

Notes:

1. Set logic gate 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 +3V to +8V 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 Vdd = +8V and A/B set to 0/+8V.
