HMC694LP4 / 694LP4E

v02.1108

Functional Diagram

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.
