Typical Applications
The HMC784MS8GE is ideal for:
• Cellular / 4G Infrastructure
• WiMAX, WiBro & Fixed Wireless
• Automotive Telematics
• Mobile Radio
• Test Equipment
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
re ective 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.
