The device is targeted for use in PDAs, VoWi-Fi handsets, cameras, cellular
handsets, computer peripherals, and automotive devices.
"As Wi-Fi technology is becoming ubiquitous more and more devices are
looking to add WiFi connectivity, in the same form factor. This is putting
pressure on the design community both in terms of board real-estate and power
budget. The RWF111 provides an effective solution for mobile electronics when
adding WiFi connectivity," said Rupert Prince, Executive Vice president, RF
Arrays, Inc. "With this new Front end device, RF Arrays is enabling OEMs to
embed Wi-Fi in a series of challenging new applications while simultaneously
shrinking form factors, extending battery life and meeting aggressive cost
targets."
The front end features a power amplifier with a current draw of less than 100
mA whilst transmitting 802.11g signal at 15 dBm output with a EVM of better than
4%. The MMIC includes a high gain very low noise LNA which will greatly improve
the link budget in most systems (LNA Gain = 15 dB, NF < 1.0 dB), as well as a
power detector and biasing circuitry in a miniature 16-pin 3 x 3 x 0.5 mm QFN
package. The FEM is fully matched internally to a 50 ohm output and input
impedance.
The RWF111 is in production now, priced at US $1.10 in 10k unit quantities.
