Its high linearity and efficiency meet the extremely demanding needs of small cell infrastructure architectures. Designed for LTE,WCDMA and HSDPA air interfaces operating in the 2.545 GHz to 2.69 GHz band, the AWB7228 delivers up to +27 dBm of LTE (E-TM1.1) power with an ACPR of -47 dBc. It operates from a convenient +4.5 V supply and provides 27 dB of gain. The device is manufactured using an advanced InGaP HBT MMIC technology offering state-of-theart reliability, temperature stability, and ruggedness. The self-contained 7 mm x 7 mm x 1.3 mm surface mount package incorporates RF matching networks optimized for output power, efficiency, and linearity in a 50 Ω system.
