VGG1 8 ACG3 1 VGG2 ACG4 2 The HMC998A is a GaAs MMIC pHEMT Distributed
Power Amplifier die which operates between DC and
22 GHz. The amplifier provides 14.5 dB of gain, 43 dBm
output IP3 and +32.5 dBm of output power at 1 dB gain
compression while requiring 500 mA quiescent current
from a +15 V supply. The HMC998A exhibits a slightly
positive gain slope, making it ideal for EW, ECM, Radar
and test equipment applications. The HMC998A amplifier I/Os are internally matched to 50 Ohms facilitating
integration into Mutli-Chip-Modules (MCMs). All data
is taken with the chip connected via two 0.025 mm
(1 mil) wire bonds of minimal length 0.31 mm (12 mils). 4 3 ACG1 AMPLIFIERS -LINEAR & POWER -CHIP GaAs pHEMT MMIC
