HMC997LC4
v02.0514 Variable Gain Amplifier -SMT VARIABLE GAIN AMPLIFIER
17 -27 GHz
Typical Applications Features The HMC997LC4 is ideal for: Wide Gain Control Range: 15 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
No External Matching • Ka-Band Radar 24 Lead 4 x 4 mm SMT Package: 16 mm2 • Test Equipment General Description Functional Diagram 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 x 4 mm ceramic QFN leadless package
and is compatible with high volume surface mount
manufacturing. Electrical Specifications, TA = +25 °C, Vdd1, 2, 3 = 5V, Vctrl = -4.5V, Idd = 170 mA*
