The O253SM7H is a GaN integrated power amplifier operating from 8 to 12 GHz. With a +28V operating voltage, it provides 22dB of power gain, 43dBm of saturated output power, and 38% power-added efficiency. The amplifier adopts 7mmx7mm surface-mount non-leaded ceramic package, which can realize gas-tight encapsulation. The surface of the pin pad is processed by gold plating and is suitable for reflow soldering installation process.
