The HMC8500 is a gallium nitride (GaN), broadband power amplifier delivering >10 W with up to 55% power added efficiency (PAE) across an instantaneous bandwidth of 0.01 GHz to 2.8 GHz, and with a ±1.0 dB typical gain flatness.
The HMC8500 is ideal for pulsed or continuous wave (CW) applications, such as wireless infrastructure, radars, public mobile radios, and general-purpose amplification.
The HMC8500 amplifier is externally tuned using low cost, surface-mount components and is available in a compact LFCSP package.
Note that throughout this data sheet, multifunction pins, such as RFIN/VGG, are referred to either by the entire pin name or by a single function of the pin, for example, RFIN, when only that function is relevant.
