Functional Diagram
General Description
The HmC972lp5e is an 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 0.5 to 6 gHz, and can be controlled to provide
anywhere from 15 db of gain to 35 db of attenuation.
The HmC972lp5e delivers noise figure of 7.5 db in
its maximum gain state, with output ip3 of up to
+28 dbm. The HmC972lp5e is housed in a roHs
compliant 5x5 mm Qfn leadless package, and requ-
ires no external matching components.
