Functional Diagram General Description
The HMC994A is a GaAs MMIC pHEMT Distrib- uted Power Amplifier which operates between DC R & P and 30 GHz. The amplifier provides 14 dB of gain, A +39 dBm output IP3 and +28 dBm of output power at E 1 dB gain compression while requiring 250 mA from IN a +10 V supply. The HMC994A exhibits a slightly positive gain slope from 2 to 20 GHz, making it ideal for EW, ECM, Radar and test equipment applica- S - L tions. With up to 39 dBm Output IP3 the HMC994A R is ideal for high linearity applications in military and IE space as well as test equipment where high order modulations are used. The HMC994A amplifier I/Os LIF are internal y matched to 50 Ohms facilitating inte- P gration into Multi-Chip-Modules (MCMs). All data M is taken with the chip connected via two 0.025 mm A (1 mil) wire bonds of minimal length 0.31 mm (12 mils).
