The SKY66299-11 is a high-efficiency 4 watt power amplifier that operates from 1900 MHz to 2000 MHz. This compact 5 x 5 mm PA is designed for FDD and TDD 2G/3G/4G LTE small cell base stations (3GPP bands covered include 2, 25, 33, 36, and 37). It has active biasing circuitry to compensate for PA performance over temperature, voltage, and process variations. It provides 4 watts of output power with a gain of 37.5 dB and requires a single 5 V supply. The amplifier is matched to 50 ohms at the input and output.
