Skyworks introduces mid- and high-power WiFi PAs

At this week’s IEEE MTT-S International Microwave Symposium (IMS 2010) in Anaheim, CA, USA (25-27 May), Skyworks Solutions Inc of Woburn, MA, USA, which makes linear products, power amplifiers, front-end modules and radio solutions for handset and infrastructure equipment, has introduced new mid- and high-power (2.4 - 2.5 gigahertz), 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, says the firm. 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, making them ideal for wireless local area network (WLAN) applications, says Skyworks. 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 SKY65152-11 and the SKY65165-11 are fabricated using Skyworks' 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. 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.

Liam K. Griffin, Skyworks’ senior vice president of sales and marketing, said: "These devices highlight Skyworks' growing suite of WiFi solutions designed to address the expanding opportunities in high-performance gateways, access points, smart phones, media, and emerging mobile Internet access platforms."

The SKY65152-11 and the SKY65165-11 are available now, with volume production scheduled to begin in the fourth quarter of this year. The SKY65152-11 is priced at $1.58 each and the SKY65165-11 is priced at $1.15 each in quantities of 10,000 devices.

Skyworks is exhibiting its products on booth #3110 at the IEEE’s MTT-S International Microwave Symposium .
