The amplifier offers integration, gain, efficiency, and wide bandwidth in a small footprint. The small device requires minimal external circuitry, which reduces overall component count and board space.
The device combines DC feed/RF bias choke, DC blocking capacitors, and driver stage on a single design, while delivering 45.5dBm (35W) with up to 44% power added efficiency (PAE) across an instantaneous bandwidth of 0.3GHz to 6GHz.
The amplifier is supported by the EVAL-HMC8205 a two-layer evaluation board that includes the HCM8205 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 attach an external heat sink for improved thermal management.
