HMC994A v04.0918 GaAs pHEMT MMIC 0.5 WATT POWER AMPLIFIER, DC - 30 GHz Typical Applications Features The HMC994A is ideal for: High P1dB Output Power: 28 dBm Test Instrumentation High Psat Output Power: 30 dBm Military & Space High Gain: 14 dB Fiber Optics High Output IP3: 39 dBm Supply Voltage: +10 V 250 mA 50 Ohm Matched Input/Output Die Size: 2.75 x 1.45 x 0.1 mm Functional Diagram General Description The HMC994A is a GaAs MMIC pHEMT Distrib- uted Power Amplifier which operates between DC and 30 GHz. The amplifier provides 14 dB of gain, +39 dBm output IP3 and +28 dBm of output power at 1 dB gain compression while requiring 250 mA from 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- tions. With up to 39 dBm Output IP3 the HMC994A is ideal for high linearity applications in military and space as well as test equipment where high order modulations are used. The HMC994A amplifier I/Os are internally matched to 50 Ohms facilitating inte- gration into Multi-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).
