General Description
The HMC950 is a four stage GaAs pHEMT MMIC
4 Watt Power Amplifier which operates between 12
and 16 GHz. The HMC950 provides 28 dB of gain,
+37 dBm of saturated output power, and 23% PAE
from a +7V power supply. The HMC950 exhibits
excellent linearity and is optimized for high capacity
point to point and point to multi-point radio systems.
It is also ideal for 13.75 to 14.5 GHz Ku Band VSAT
transmitters as well as SATCOM applications. The
amplifier configuration and high gain make it an
excellent candidate for last stage signal amplification
before the antenna. 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.
