General Description
Functional Diagram
The HMC518 chip is a high dynamic range GaAs
PHEMT MMIC Low Noise Amplifier (LNA) which
covers the 20 to 32 GHz frequency range. The
HMC518 provides 15 dB of small signal gain, 3 dB
of noise figure and has an output IP3 greater than
23 dBm. The chip can easily be integrated into hy-
brid or MCM assemblies due to its small size. All data
is tested with the chip in a 50 Ohm test fixture con-
nected via 0.075mm (3 mil) ribbon bonds of minimal
length 0.31 mm (12 mil). Two 0.025 mm (1 mil) diameter
bondwires may also be used to make the RFIN and
RFOUT connections.
