HMC462
v02.0213 Amplifiers -Low Noise Amplifiers -Chip GaAs pHEMT MMIC
LOW NOISE AMPLIFIER, 2 -20 GHz
Typical Applications Features The HMC462 is ideal for: Noise Figure: 2 dB • Test Instrumentation Gain: 15 dB • Microwave Radio & VSAT P1dB +15.5 dBm • Military & Space Self-Biased: +5V @ 63 mA • Telecom Infrastructure 50 Ohm Matched Input/Output • Fiber Optics Die Size: 3.0 x 1.3 x 0.1 mm Functional Diagram General Description
The HMC462 is a GaAs MMIC pHEMT Low Noise
Distributed Amplifier which operates between 2
and 20 GHz. The amplifier provides 15 dB of small
signal gain, 2.5 dB noise figure, and up to +15.5 dBm
of output power at 1dB compression. Gain flatness
is excellent at ±0.3 dB from 8 -14 GHz making the
HMC462 ideal for EW, ECM, and Radar applications.
The HMC462 requires a single supply of +5V @ 63
mA and is the self biased version of the HMC463.
The wideband amplifier I/Os are internally matched
to 50 Ohms facilitating integration into Multi-ChipModules (MCMs). All data is measured with the chip in
a 50 Ohm test fixture connected via 0.025 mm (1 mil)
diameter wire bonds of 0.31 mm (12 mils) length. Electrical Specifications, TA = +25° C, Vdd = +5V, Idd = 63 mA
