HMC6187LP4E v00.0312 VARIABLE GAIN AMPLIFIER 27 - 31.5 GHz Typical Applications Features Variable Gain Amplifier - SMT The HMC6187LP4E is ideal for: Wide Gain Control Range: 13 dB • Point-to-Point Radio Single Control Voltage • Point-to-Multi-Point Radio Output IP3 @ Max Gain: +31 dBm • EW & ECM Subsystems Output P1dB: +24 dBm • Ka-Band Radar & VSAT No External Matching • Test Equipment 24 Lead 4x4 mm SMT Package: 16 mm2 Functional Diagram General Description The HMC6187LP4E is a GaAs MMIC pHEMT analog variable gain amplifier and/or driver amplifier which operates between 27 and 31.5 GHz and is ideal for microwave radio applications. The amplifier provides up to 19 dB of gain, output P1dB of up to +24 dBm, and up to +31 dBm of output IP3 at maximum gain, while requiring 230 mA from a +5V supply. A gain control voltage (Vctrl) is provided to allow variable gain control up to 13 dB. Gain flatness is excellent making the HMC6187LP4E ideal for EW, ECM and radar applications. The HMC6187LP4E is housed in a RoHS compliant 4 x 4 mm plastic QFN leadless package and is compatible with high volume surface mount manufacturing.
