-11.5 to 20 dB Gain Control in 0.5 dB Steps

High Output IP3: +36 dBm

TTL/CMOS Compatible Serial or Parallel Control

±0.25 dB Typical Gain Step Error

Single +5V Supply

The HMC627LP5(E) is a digitally controlled variable

gain amplifier which operates from DC 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 HMC627LP5(E) 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 HMC627LP5(E) also features a

user selectable power up state and a serial output for

cascading other Hittite serially controlled components.

The HMC627LP5(E) is housed in a RoHS compliant

5x5 mm QFN leadless package, and requires no

external matching components.
