High RF power Capabilty
General Description
The HMC174MS8 is a low-cost SPDT switch in
an 8-lead MSOP package for use in transmit-
receive applications which require very low dis-
tortion at high signal power levels. The device
can control signals from DC to 3.0 GHz and is
especially suited for 900 MHz, 1.8 - 2.2 GHz, and
2.4 GHz ISM 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 reflec-
tive 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.
