General Description
The HMC626ALP5E is a digitally controlled variable
gain amplifier which operates from DC to 1 GHz, and
can be programmed to provide anywhere from 8.5 dB,
to 40 dB of gain, in 0.5 dB steps. The HMC626ALP5E
delivers noise figure of 2.8 dB in its maximum gain
state, with output IP3 of up to +36 dBm in any state.
This single positive control line per bit digital VGA
incorporates off chip AC ground capacitors for near
DC operation, making it suitable for a wide variety of
RF and IF applications. The HMC626ALP5E is housed
in a RoHS compliant 5x5 mm QFN leadless package,
and requires no external matching components. A
serial control version of this product is available as the
HMC681ALP5E.
