General Description
The HMC646LP2(E) is an SPDT switch in a leadless
DFN surface mount plastic package for use in trans-
mit / receive and LNA protection applications which
require very low distortion and high power handling
of up to 40 watts with less than 10% duty cycle. This
robust switch can control signals from 100 - 2100
MHz* and is ideal for TD-SCDMA / 3G repeaters,
PMR, automotive telematics, and satellite subscriber
terminal applications. The design provides excep-
tional P0.1dB of +46 dBm and +74 dBm IIP3 on the
Transmit (Tx) port. The failsafe topology provides a
low loss path from Tx to RFC, when no DC power is
available.
