Highly Integrated WiFi Front End Module for High-Performance Dual-Band Applications
RF Micro Devices, Inc. (RFMD) announces the release of the RF5608 WiFi RF front end module (FEM). RFMD's feature-rich RF5608 FEM delivers superior integration and full final testing to reduce size, simplify development and lower overall cost in high-performance, dual-band applications such as mobile computing and access point WiFi applications. The dual-band RF5608 integrates components for the 2.4 GHz to 2.5 GHz and 4.9GHz to 5.85GHz ISM bands, including power amplifiers (PAs), low noise amplifiers (LNAs), power detector circuitry and a diplexer with full harmonic filtering. The integrated power detector provides a highly accurate voltage to enable closed loop power control and help reduce system test time and calibration needs. The three-stage PAs provide high linear output power of 18 dBm in the 2.4 GHz to 2.5 GHz frequency range and 16 dBm in the 4.9 GHz to 5.85 GHz frequency range. The PAs are also fully tested, including for DC and RF parameters (including EVM). The RF5608 also features a full, integrated RF matching network to minimize external SMD requirements and an optimized supply voltage to increase compatibility with multiple applications.
