Functional Diagram

General Description

The HMC681ALP5E is a digitally controlled variable

gain ampliﬁer which operates from DC to 1 GHz,

and can be programmed to provide anywhere from

13.5 dB, to 45 dB of gain, in 0.5 dB steps. The

HMC681ALP5E delivers noise ﬁgure of 2.8 dB in its

maximum gain state, with output IP3 of up to +36

dBm in any state. This serially controlled 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 HMC681ALP5E is housed

in a RoHS compliant 5x5 mm QFN leadless package,

and provides the user with a highly integrated solution.

This functionality is also available with parallel control

as the HMC626ALP5E.
