GaAs, pHEMT, MMIC, Single Positive Supply, DC to 10 GHz Power Amplifier

The ADPA9002 is a gallium arsenide (GaAs), pseudomorphic high electron mobility transistor (pHEMT), monolithic microwave integrated circuit (MMIC), power amplifier that operates between dc and 10 GHz. The amplifier provides 15 dB of gain, 42 dBm of OIP3, and 31.5 dBm of saturated output power (PSAT) while requiring 385 mA from a 12 V supply. The ADPA9002 is self biased in normal operation and has an optional bias control for supply quiescent current (IDQ) adjustment. The amplifier is ideal for military and space and test equipment applications. The ADPA9002 also features inputs and outputs that are internally matched to 50 Ω, housed in a RoHS compliant, 5 mm × 5 mm LFCSP premolded cavity package, making it compatible with high volume surface-mount technology (SMT) assembly equipment.

Note that throughout this data sheet, multifunction pins, such as RFOUT/VDD, are referred to either by the entire pin name or by a single function of the pin, for example, VDD, when only that function is relevant.
