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.
