General Description
The HMC627ALP5E is a digitally controlled variable
gain amplifier which operates from 50 MHz to 1 GHz,
and can be programmed to provide anywhere from
11.5 dB attenuation, to 20 dB of gain, in 0.5 dB steps.
The HMC627ALP5E delivers noise figure of 4.3 dB
in its maximum gain state, with output IP3 of up to
+36 dBm in any state. The dual mode gain control
interface accepts either three wire serial input or 6
bit parallel word. The HMC627ALP5E also features a
user selectable power up state and a serial output for
cascading other Hittite serially controlled components.
The HMC627ALP5E is housed in a RoHS compliant
5x5 mm QFN leadless package, and requires no
external matching components.

The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown.
A sufficient number of via holes should be used to
connect the top and bottom ground planes. The
evaluation circuit board shown is available from Hit-
tite upon request.
