Functional Diagram
General Description
The HMC484MS8G & HMC484MS8GE are low-
cost SPDT switches in 8-lead MSOPG packages for
use in transmit-receive applications which require
very low distortion at high input signal power levels,
through 10 watts (+40 dBm). The device can control
signals from DC to 3.0 GHz. The design provides
exceptional intermodulation performance; > +70 dBm
third order intercept at +5 volt bias. RF1 and RF2
are reflective shorts when “OFF”. On-chip circuitry
allows single positive supply operation from +3 Vdc
to +10 Vdc at very low DC current with control inputs
compatible with CMOS and most TTL logic families.
