Skyworks Solutions, Inc. introduces new mid- and high-power (2.4 to 2.5 GHz), highly efficient power amplifiers (PAs) for 802.11n multiple in/multiple out (MIMO) access points, routers and gateways. These high-performance, small form factor solutions enable multiple-transmit channels on printed circuit boards (PCBs), offering customers valuable configuration space savings. In addition, the mid-power PA offers two operating points in a single-device, providing maximum customer flexibility when developing platforms that meet varying performance requirements. The SKY65152-11 (20-pin, 6 x 6 mm) and the SKY65165-11 (16-pin, 3 x 3 mm) are microwave monolithic integrated circuit (MMIC) PAs with superior output power, linearity, and efficiency. These features make the PAs suited for wireless local area network (WLAN) applications. The high linearity, low EVM and high efficiency of these devices also make them ideal for use in the transmit chain of WLAN access points and modems. The devices are fabricated using Skyworks' high reliability heterojunction bipolar transistor (HBT) indium gallium phosphide (InGaP) process, which allows for single supply operation while maintaining high efficiency and good linearity. The SKY65152-11 is a fully-matched PA, incorporating a directional power coupler for accurate power detection, mounted in a multi-chip module (MCM) package, and the SKY65165-11 is internally matched at the radio frequency (RF) input, includes integrated power detector, biasing and is mounted in a quad flat no-lead (QFN) surface-mounted technology (SMT) package, which allows for a highly manufacturable low-cost solution.
