Fairchild Semiconductor released an RF Power Amplifier Module (PAM) for high-performance WLAN applications in the 2.4GHz to 2.5GHz frequency band.

Engineered for 802.11b/g applications, the RMPA2453 features an Error Vector Magnitude (EVM) performance of 2.5 percent. The linear power amplifier's low power consumption and linearity are the result of Fairchild's proprietary InGaP Heterojunction Bipolar Transistor (HBT) technology.

Russ Wagner, GM of Fairchild's RF power products group, said that they are already shipping the new device in high volume because of its superior EVM, low power consumption and matched PA module. "The RMPA4253's superior linearity is evidenced by its 2.5 percent EVM performance - one of the industry's best within the 802.11 b/g band," he added.

The RMPA2453 power amplifier internally matches both the input and output to 50 ohms, and provides an on-chip power-sensing detector with dual power-saving shutdown options.

Priced at 60 cents each in 100,000-piece quantities, other key features of the linear power amp include two power-saving shutdown options (bias and logic control) that minimize power consumption while maintaining performance, and an integrated power detector with 20dB dynamic range that reduces BOM.
