HMC195

v01.0700

Typical Application Circuit

GaAs MMIC SOT26 T/R

SWITCH, DC - 2.5 GHz

Notes:

1. 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 8 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 V set to +10V. The switch will operate properly (but at lower

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