Functional Diagram
General Description
The HMC441 is an efficient GaAs PHEMT MMIC
Medium Power Amplifier which operates between 6
and 18 GHz*. The amplifier provides 15.5 dB of gain,
+22 dBm of saturated power, and 23% PAE from a
+5V supply voltage. An optional gate bias is provided
to allow adjustment of gain, RF output power, and DC
power dissipation. The HMC441 amplifier can easily
be integrated into Multi-Chip-Modules (MCMs) due
to its small size. The backside of the die is both RF
and DC ground, simplifying the assembly process
and reducing performance variation. All data is tested
with the chip in a 50 Ohm test fixture connected via
0.025mm (1 mil) diameter wire bonds of minimal length
0.31mm (12 mils).
