GENERAL DESCRIPTION
The HMC349ALP4CE is a gallium arsenide (GaAs), single-pole,
double throw (SPDT) switch, specified from 100 MHz to 4 GHz.
The HMC349ALP4CE is well suited for wireless infrastructure
applications by yielding high isolation of 62 dB, low insertion
loss of 1.0 dB, high input IP3 of 53 dBm, and high input P1dB
of 34 dBm.
Rev. B
The HMC349ALP4CE operates with a single, positive supply
voltage from 3 V to 5 V and provides a CMOS-/TTL-compatible
control interface.
The HMC349ALP4CE comes in a 16-lead, 4 mm × 4 mm,
RoHS compliant, lead frame chip scale package (LFCSP).
