RF power amp module chosen by motherboard manufacturers

South Portland, Maine — Fairchild Semiconductor, a global supplier of high-performance products for power optimization, announces the RMPA2455, a new RF Power Amplifier Module (PAM) for high-performance Wireless LAN (WLAN) client and access point applications in the 2.4-2.5 GHz frequency band. The device's unique combination of 30 dBm output power, 30 dB small signal gain and 3 x 3 mm low-profile leadless package provides stand-out performance unmatched by any competitive device in the industry. These performance attributes make the RMPA2455 the optimal linear power amplifier design choice for the 5V environment, providing industry-leading performance in a substantially smaller footprint package compared to alternative PAM solutions.

The RMPA2455 device's low-profile, 16-pin, 3 x 3 x 0.9 mm QFN package with 50 Ohm internal matching on both the input and output minimizes next-level PCB space requirements and simplifies integration. The device's on-chip detector provides power-sensing capability while the logic capability provides power-saving shutdown options. The RMPA2455's low power consumption and excellent linearity are the result of Fairchild's proprietary InGaP Heterojunction Bipolar Transistor (HBT) technology.

“The RMPA2455's industry-leading performance in the form of 30 dB small signal gain and 3% EVM at 22 dBm modulated power output are the primary reasons why Fairchild was designed into the premier standard platform of one of the world's largest PC motherboard manufacturers,” says Russ Wagner, general manager of Fairchild's RF power products group. “Now available in high-volume production quantities, the RMPA2455 device expands Fairchild's growing family of 3 x 3 and 4 x 4 mm RF power amplifiers.”

Other key features and specifications of the RMPA2455 power amplifier include:

* Full optimization for 802.11b/g access point applications;
* 5.0 V positive collector supply operation;
* Bias and logic control power-saving shutdown options;
* Integrated power detector with 20 dB dynamic range;
* DC blocked RF input/output.

The RMPA2455 price is $0.85 each in 100,000 piece lots, is available now with a delivery of 8 weeks ARO.
