32 Lead 5x5 mm SMT Package: 25 mm2 Functional Diagram 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. Electrical Specifications, TA = +25° C, 50 Ohm System Vdd = +5V, Vs= +5V
