SiGe SE2523BU, Tiny WiFi RF Power Amplifier for Portable Embedded Wireless

SiGe announced (August 14, 2006 ) their new WiFi power amplifier RangeCharger SE2523BU. SiGe claims, the chip is a world’s tinniest WiFi power amplifier.

The SE2523BU delivered in 16-pin 3 x 3 x 0.5 mm QFN package, implement paper-thin packaging technology for this RangeCharger™ SE2523BU chip, giving a profile of just 0.5mm. The ultra-thin property of this chip also reduce power consumption by 25% (drawn 130 mA at +18.5 dBm output power with 3.3 V supply).

The ultra tiny size and small power consumption make this chip ideal for portable embedded WiFi  applications, including PDAs, VoWi-Fi handsets, cameras, cellular handsets, computer peripherals, and automotive devices.

The SE2523BU features +18.5dBm power output with EVM of 2.5% in 802.11g mode. All ACPR requirements are met while operating at +23dBm output power in 802.11b mode.

Integrated power detector improves stability of wireless transmissions, since it is highly immune to mismatch: less than 1.5dB of variation with a 2:1 mismatch.

The power detector offers positive or negative power detector slopes, allowing it to be used with multiple chipsets. Also incorporated on chip is digital enable control circuitry, which eases design by allowing the device to be connected directly to a CMOS baseband or transceiver.

To support development, SiGe also offers SE2523BU-EK1, an Evaluation Kit for this chip.

Availability and Price: The SE2523BU is in production now, priced at US $.79 in 10k
