General Description Functional Diagram
The HMC998A is a GaAs MMIC pHEMT Distributed R & P Power Amplifier die which operates between DC and A 3 4 22 GHz. The amplifier provides 14.5 dB of gain, 43 dBm E ACG1 ACG2 output IP3 and +32.5 dBm of output power at 1 dB gain IN VGG2 5 compression while requiring 500 mA quiescent current 2 RFOUT & from a +15 V supply. The HMC998A exhibits a slightly VDD positive gain slope, making it ideal for EW, ECM, Radar S - L and test equipment applications. The HMC998A ampli- R fier I/Os are internal y matched to 50 Ohms facilitating 1 IE RFIN integration into Mutli-Chip-Modules (MCMs). All data ACG4 ACG3 VGG1 8 7 6 is taken with the chip connected via two 0.025 mm LIF (1 mil) wire bonds of minimal length 0.31 mm (12 mils). P M A
