RF Arrays Delivers World's Smallest Wi-Fi Integrated Front End

(Product News, 14 Apr 2007)

RF Arrays Inc. has released the world's smallest front end solution for Wi-Fi systems. The RWF111 delivers industry-leading performance for both Power and Low Noise Amplifier and antenna switch in a 3x3mm package and an external component count of just 2 bi-pass capacitors. The ultra small footprint also reduces power amplifier power consumption significantly vs. currently available solutions, making it ideal for embedding Wi-Fi capability into portable, battery-powered consumer electronics.

The device addresses the growing demand for embedded Wi-Fi capability in electronic equipment where board space is at a premium and power consumption needs to be minimized. Target devices include PDAs, VoWi-Fi handsets, cameras, cellular handsets, computer peripherals, and automotive devices.

The ultra compact front end features a power amplifier with a current draw of less than 100mA while transmitting 802.11g signal at 15dBm output with a EVM of better than 4 percent. The MMIC includes a high gain very low noise LNA which will greatly improve the link budget in most systems (LNA Gain = 15dB, NF <1dB), as well as a power detector and biasing circuitry in a miniature 16-pin 3x3x0.5mm QFN package. The FEM is fully matched internally to a 50Ω output and input impedance.
