• IF & RF Applications

General Description

the HmC625Hflp5e is a digitally controlled variable

gain amplifier which operates from 0.5 - 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

HmC625Hflp5e 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 HmC625Hflp5e also

features a user selectable power up state and a serial

output port for cascading other Hittite serial controlled

components. the HmC625Hflp5e is housed in a

roHs compliant 5 x 5 mm Qfn leadless package, and

requires no external matching components.
