Functional Diagram
General Description
The HmC694lp4(e) is a gaas mmiC pHemT analog variable gain amplifier which operates between 6 and 17 gHz. ideal for microwave radio applications, the amplifier provides up to 22 db of gain, output p1 db of up to +22 dbm, and up to +30 dbm of output ip3 at maximum gain, while requiring only 175 ma from a +5V supply. a gate bias pin (Vctrl) is provided to allow variable gain control up to 23 db. gain flatness is excellent making the HmC694lp4e ideal for eW, eCm and radar applications. The HmC694lp4e is housed in a roHs compliant 4x4 mm Qfn leadless package and is compatible with high volume surface mount manufacturing.
