SiGe Semiconductor Intros SE2522L Power Amplifier

August 28, 2002 by Jeff Shepard

SiGe Semiconductor Inc. (Ottawa, ON, Canada) announced its new SE2522L 2.4GHz power amplifier, which combines a SiGe architecture with power control circuitry to reduce current consumption by as much as 50 percent over competing products. A part of the company's RangeCharger product line, the eight-lead PLCC device is based on the SE2520L device and is expected to drive 802.11b-enabled laptops, computer peripherals, cellular phones and other hand-held computing devices.

The SE2522L uses SE2520L's architecture but adds a power detector to augment the performance and simplify design of WLAN systems on a CMOS radio. Capable of operating at full duty cycle, the amplifier delivers up to 20dBm of linear output power with an adjacent-channel power ratio <-20dBm per 100kHz. The device operates from a single 3.3V supply and draws 110mA.

Aside from the LPCC package, the SE2522L will also be available in a flip-chip package option. Pricing is $0.94 in 100,000-unit quantities.
