General Description
The HMC992LP5E is an IF analog controlled variable
gain amplifier composed of two identical voltage
variable attenuators in combination with an InGaP
HBT gain block MMIC amplifier which operates from
0.1 to 0.8 GHz, and can be controlled to provide
anywhere from -10 dB attenuation, to 40 dB of gain.
The HMC992LP5E delivers noise figure of 6 dB in
its maximum gain state, with output IP3 of up to
+40 dBm. The HMC992LP5E is housed in a RoHS
compliant 5x5 mm QFN leadless package, and requ-
ires no external matching components.
