HMC997LC4 v02.0514 VARIABLE GAIN AMPLIFIER 17 - 27 GHz Typical Applications Features The HmC997l C4 is ideal for: Wide Gain Control r ange: 15 db Single Control Voltage point-to-point r adio Output ip3 max Gain: +31 dbm point-to-multi-point r adio Output p1db: +24 dbm eW & eCm Subsystems n o external matching Ka- band r adar 2 24 l ead 4 x 4 mm SmT package: 16 mm T est equipment General Description Functional Diagram The HmC997l C4 is a Gaas mmiC pHemT analog variable gain amplifier and/or driver amplifier which operates between 17 and 27 GHz. ideal for microwave radio applications, the amplifier provides up to 20.5 db of gain, output p1db of up to +24 dbm, and up to +31 dbm of output ip3 at maximum gain, while requiring only 170 ma from a +5V supply. a gain control voltage (Vctrl) is provided to allow variable gain control up to 15 db. Gain flatness is excellent making the HmC997l C4 ideal for eW, eCm and radar applications. The HmC997l C4 is housed in a r oHS compliant 4 x 4 mm ceramic Qfn leadless package and is compatible with high volume surface mount manufacturing.
