RF power amp for WLAN improves EVM
Fairchild Semiconductor has announced the RMPA2453, a linear RF power amplifier module (PAM) for high-performance wireless local-area network (WLAN) applications in the 2.4–2.5 GHz frequency band. Optimized 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. The 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.
Key features and specifications of the RMPA2453 linear power amp include:
- 2.5 percent EVM at 18 dBm output provides superior
- Matched PA module operating with 3.3 V single supply minimizes the need for peripheral components, reducing overall BOM costs.
- Two power-saving shutdown options (bias and logic control) minimize power consumption while maintaining performance.
- Integrated power detector with 20 dB dynamic range reduces BOM.
- Ideal for use in WLAN routers, access points and adapter cards, and USB dongles.
