Functional Diagram
General Description
The HMC784MS8GE is a high power SPDT switch in
an 8-lead MSOPG package for use in transmit-rece-
ive applications which require very low distortion at
high input signal power levels. The device can con-
trol 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.
