- Buyers Guide
The RF5325, RF5345, and RF5725 FEMs each contain a 2.4 GHz power amplifier (PA) designed to optimize linearity while minimizing current consumption--a critical requirement in battery powered devices. Each FEM integrates an output power coupler, transmit (Tx) low pass filtering and a single-pole three-throw (SP3T) switch capable of switching between Wi-Fi receive (Rx), Wi-Fi Tx, and Bluetooth(R) Rx/Tx operations. The integrated coupler significantly lowers bill-of-material (BOM) costs and reduces the board area necessary for front end implementation in chipsets utilizing closed loop power control to adjust output power. The RF5345 and RF5725 also integrate a low noise amplifier (LNA) for RF architectures requiring additional Rx gain.
"We are very pleased to expand our portfolio of Wi-Fi front ends to address the growing opportunities in Wi-Fi-enabled mobile devices," said Rohan Houlden, general manager of RFMD's Wireless Connectivity Business Unit. "These highly integrated FEMs offer mobile device designers a single placement front end solution that reduces footprint and minimizes component count while delivering an optimal blend of high linearity and low power consumption."
Technical features of the RF5325, RF5345, and RF5725 include:
-- Compact, low profile packages: 3.0 x 3.0 x 0.5 mm
-- Low external component count
-- Designed for operation in 802.11 b/g/n systems
-- Excellent linearity, 3.3% error vector magnitude (EVM)
-- Integrated output power coupler
