Overview
The HMC943APM5E is a high-performance, four-stage gallium arsenide (GaAs) pseudomorphic high electron mobility transistor (pHEMT) monolithic microwave integrated circuit (MMIC) power amplifier. Developed by Analog Devices Inc., this device operates within the frequency range of 24 GHz to 34 GHz, making it ideal for various microwave radio applications. The amplifier provides 23 dB of gain, 34 dBm of saturated output power (PSAT), and a power added efficiency (PAE) of 23% from a 5.5 V supply. Its high output third-order intercept (IP3) of 39 dBm and integrated power detector output further enhance its suitability for demanding applications.
