Functional Diagram
General Description
The HMC342 chip is a GaAs MMIC Low Noise
Amplifier (LNA) which covers the frequency range
of 13 to 25 GHz. The chip can easily be inte-
grated into Multi-Chip Modules (MCMs) due to its
small (2.14 mm2) size. The chip utilizes a GaAs
PHEMT process offering 20 dB gain from a single
bias supply of + 3.0V @ 36 mA with a noise figure
of 3.5 dB. All data is with the chip in a 50 ohm
test fixture connected via 0.025 mm (1 mil) diam-
eter wire bonds of minimal length 0.31 mm (<12
mils).
