-13.5 to +18 Gain Control in 0.5 dB Steps

High Output IP3: +33 dBm

TTL/CMOS Compatible Serial or Parallel Control

±0.25 dB Typical Gain Step Error

Single +5V Supply

The HMC625LP5(E) is a digitally controlled variable

gain amplifier which operates from DC to 6 GHz, and

can be programmed to provide anywhere from 13.5

dB attenuation, to 18 dB of gain, in 0.5 dB steps. The

HMC625LP5(E) delivers noise figure of 6 dB in its

maximum gain state, with output IP3 of up to +33 dBm

in any state. The dual mode control interface is CMOS/

TTL compatible, and accepts either a three wire serial

input or a 6 bit parallel word. The HMC625LP5(E) also

features a user selectable power up state and a serial

output port for cascading other Hittite serial controlled

components. The HMC625LP5(E) is housed in a

RoHS compliant 5x5 mm QFN leadless package, and

requires no external matching components.
