The HMC997LC4 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 HMC997LC4 ideal for EW, ECM and radar applications. The HMC997LC4 is housed in a RoHS compliant 4 × 4 mm ceramic QFN leadless package and is compatible with high volume surface mount manufacturing.
