Typical Applications
The HMC174MS8(E) is ideal for:
• Infrastructure & Repeaters
• Cellular/3G & WiMAX
• Portable Wireless
• LNA Protection
• Automotive Telematics
• Test Equipment
The HMC174MS8 & HMC174MS8E are low-cost
SPDT switches in 8-lead MSOP packages for use in
transmit-receive applications which require very low
distortion at high signal power levels. The device can
control signals from DC to 3 GHz and is especially
suited for cellular/3G and WiMAX applications with
only 0.5 dB loss. The design provides exceptional
intermodulation performance; providing a +60 dBm
third order intercept at 8 Volt bias. RF1 and RF2 are
re ective shorts when “OFF”. On chip circuitry allows
single positive supply operation at very low DC current
with control inputs compatible with CMOS and most
TTL logic families.
