Functional Diagram
General Description
The HmC903 is a self-biased GaAs mmiC low
Noise Amplifier which operates between 6 and 18
GHz. This lNA provides 19 dB of small signal gain,
1.6 dB noise figure, and output ip3 of 27 dBm, while
requiring only 90 mA from a +3.5 V supply. The p1dB
output power of 16 dBm enables the lNA to function
as a lo driver for balanced, i/Q or image reject
mixers. The HmC903 also features i/os that are DC
blocked and internally matched to 50 ohms for ease
of integration into multi-chip-modules (mCms). All
data is taken with the chip in a 50 ohm test fixture
connected via 0.025 mm (1 mil) diameter with bonds
of 0.31 mm (12 mils) length.
