The Analog Devices HMC8205 GaN MMIC amplifier, available from Mouser Electronics, offers unparalleled integration, gain, efficiency, and bandwidth in a compact form factor. The small device requires minimal external circuitry, reducing the overall component count and board space.
The HMC8205 combines DC power/RF choke bias, DC blocking capacitors, and driver phase in a single design, while delivering 45.5 dBm (35 watts) with up to 44 percent power efficiency (PAE) across an instantaneous bandwidth of 0.3 GHz to 6 GHz. The amplifier is compatible with the EVAL-HMC8205, a two-layer evaluation board that includes the HMC8205 amplifier, 50-ohm coaxial RFIN and RFOUT connectors, and a copper heat spreader for thermal relief. The board also includes mounting holes that allow engineers to install an external heatsink for improved thermal management.
