• Manufacturer Part Number: hmc595e
• Description: Gaas Mmic 3 Watt T/r Switch, Dc - 3 Ghz
• Manufacturer: Hittite Microwave Corporation

Pin Descriptions
Typical Application Circuit
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.
