General Description
The HMC680LP4(E) is a digitally controlled variable
gain amplifier which operates from 30 to 400 MHz,
and can be programmed to provide -4 dB to +19 dB of
gain, in 1 dB steps. The HMC680LP4(E) delivers noise
figure of 5 dB in its maximum gain state, with output
IP3 of up to +40 dBm in any state. This high linearity
DVGA also provides a differential RF output which can
be used to interface directly with SAW filters in Tx and
Rx applications, and with digital to analog converters
in Rx chains. The HMC680LP4(E) is housed in a
RoHS compliant 4x4 mm QFN leadless package, and
is CMOS/ TTL compatible.
