Atmel Announces The Only WiMAX Transceiver with Internal Calibration

Atmel® Corporation (NASDAQ: ATML) announced today the third of its MAX-Link™ series of transceivers designed specifically for WiMAX applications. AT86RF525B and its predecessor, the AT86RF535B, use a proprietary internal calibration algorithm eliminating the need for an external calibration circuit or calibration software.

Transparent Internal Calibration Improves Performance without Disrupting Operation and Cuts Cost by Eliminating the Need for External Calibration Circuitry or Calibration Software The MAX-Link™ transceivers are the only WiMAX specific transceivers on the market today with internal calibration. Initial startup calibration captures mismatch effects resulting in lower local oscillator leakage and improved image rejection. Changes in temperature, supply voltage, or frequency during operation will cause RF performance degradation and necessitates recalibration. The calibration routine is continuously performed between transmit and receive data frames, totally independent from the baseband and media access control (MAC) processor, to optimize the image rejection and LO leakage performance characteristics.
