General Description
The HMC968 is a 4 stage GaAs pHEMT MMIC 1
Watt Power Amplifier which operates between 40 and
43.5 GHz. The HMC968 provides 21 dB of gain, +32
dBm of saturated output power, and 15% PAE from
a +6V supply. With a very good IP3 performance of
+38 dBm, the HMC968 is ideal for linear applications
including point-to-point and point-to-multi-point ra-
dios. All data is taken with the chip in a 50 Ohm test
fixture connected via (2) 0.025 mm (1 mil) diameter
wire bonds of 0.31 mm (12 mil) length.
