General Description
Functional Diagram
LE
The HMC784MS8GE is a high power SPDT switch in
an 8-lead MSOPG package for use in transmit-receive applications which require very low distortion at
high input signal power levels. The device can control signals from DC to 4 GHz. The design provides
exceptional intermodulation performance; > +60 dBm
third order intercept at +5V bias. RF1 and RF2 are
reflective shorts when “OFF”. On-chip circuitry allows
single positive supply operation from +3 Vdc to +8 Vdc
at very low DC current with control inputs compatible
with CMOS and most TTL logic families.

Notes:
1. Set logic gate and switch Vdd = +3V to +8V 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 and to pin 4 of the RF switch.
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 +8V. The switch will operate properly (but at lower
RF power capability) at bias voltages down to +3V.
