HMC996LP4E v01.0112 Variable Gain Amplifier - SMT VARIABLE GAIN AMPLIFIER 5 - 12 GHz Typical Applications Features The HMC996LP4E is ideal for: Wide Gain Control Range: 22 dB * Point-to-Point Radio Single Control Voltage: -1 to -4.5V * Point-to-Multi-Point Radio Output IP3 @ Max Gain: +34 dBm * EW & ECM Subsystems Output P1dB: +22 dBm Low Noise Figure 2dB @ max gain * X-Band Radar No External Matching * Test Equipment & Sensors 24 Lead 4x4 mm SMT Package: 16 mm2 Functional Diagram General Description The HMC996LP4E is a GaAs PHEMT MMIC analog variable gain amplifier and / or driver amplifier which operates between 5 and 12 GHz. Ideal for microwave radio applications, the amplifier provides up to 18.5 dB of gain, output P1dB of up to +23 dBm, and up to +34 dBm of output IP3 at maximum gain, while requiring only 170 mA from a +5V supply. Gain control voltage pin (Vctrl) is provided to allow variable gain control up to 22 dB. Gain flatness is excellent making the HMC996LP4E ideal for EW, ECM and radar applications. The HMC996LP4E is housed in a RoHS compliant 4 x 4 mm QFN leadless package and is compatible with high volume surface mount manufacturing.
