Functional Diagram
General Description
The HMC490 is a high dynamic range GaAs
PHEMT MMIC Low Noise Ampli鏗乪r which
operates between 12 and 17 GHz. The HMC490
provides 27 dB of gain, 2 dB noise 鏗乬ure and an
output IP3 of 35 dBm from a +5.0 V supply voltage.
The ampli鏗乪r chip can easily be integrated into
Multi-Chip-Modules (MCMs) due to its small size.
All data is tested with the chip in a 50 Ohm test
鏗亁ture connected via 0.025mm (1 mil) diameter
wire bonds of minimal length 0.31mm (12 mils).
