SiGe Semiconductor Debuts SE2529L Power Amplifier

February 06, 2003 by Jeff Shepard

SiGe Semiconductor Inc. (Canada) introduced the new RangeCharger™ SE2529L multi-mode, three-stage power amplifier that specifically targets 2.4GHz WLAN systems compliant to the IEEE 802.11b and 802.11g (draft) specifications. The power amplifier delivers 18dBm of output power while meeting an adjacent channel power ratio (APCR) of -29 (11MHz offset) and -43 (20MHz offset) in 802.11g mode. In 802.11b mode, the device delivers 23dBm at an APCR <32dBc on the first side lobe and <50dBc on the second side lobe.

The SE2529L achieves the output performance with a SiGe architecture suited to meet OFDM implementations. The architecture also features a 32dB gain and an error vector magnitude that complies with the IEEE 802.11g (draft) specification. The SE2529L consumes less than 200mA while transmitting at 54Mbps data rates.

The SE2529 is sampling in 4mm x 4mm, 12-pin, LPCC packages and is priced at $1.08 each in 10,000-unit quantities.
