Features
Noise Figure : 3.5 dB
Gain: 20 dB
Single Supply : +3V @ 41mA
Small Size: 1.06 x 2.02 mm
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 integrated
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 +3V @ 41mA with a noise figure of 3.5 dB.
All data is with the chip in a 50 ohm test fixture con-
nected via 0.025 mm (1 mil) diameter wire bonds of
minimal length 0.31 mm (<12 mils).
Electrical Specifications, T_A = +25° C, Vdd = +3V
