September 18, 2019 - Irvine, California - Skyworks is pleased introduce the SKY66318-11, a new addition to our family of high-efficiency power amplifiers (PA) that are designed for the stringent requirements of enterprise small cell applications. The PA offers wide instantaneous bandwidth (100 MHz) and is fully input/output matched with high gain and efficiency. On-chip active biasing circuitry is also integrated to compensate for PA performance over temperature, voltage, and process variations. The device comes in a compact 5 x 5 mm package, operates from a single 5 V power supply, and is ideal for 4G LTE and 5G NR systems from 3300 to 3600 MHz. The SKY66318-11 is also part of major transceiver reference designs.

Features

Wide instantaneous signal bandwidth: 100 MHz
