Functional Diagram
General Description
The HMC574MS8 & HMC574MS8E are low-cost
SPDT switches in 8-lead MSOP packages for use
in transmit/receive applications which require very
low distortion at high incident power levels. The
device can control signals from DC to 3 GHz and
is especially suited for Cellular/3G infrastructure,
WiMAX and WiBro applications with only 0.3 dB
typical insertion loss. The design provides 5 watt
power handling performance and +65 dBm third
order intercept at +8 Volt bias. RF1 and RF2 are
reflective shorts when “Off”.
