RFMD Launches 2.4GHz ISM Band Transceiver

(Product News, 7 May 2008)

RF Micro Devices Inc. (RFMD) has released ML2726, a low power, low-IF, frequency shift key (FSK) transceiver targeted at the ISM band. Designed for operation in the license-free 2.4GHz band, the ML2726 reference design enables consumer product original equipment manufacturers (OEMs) to quickly bring to market products featuring wireless data connectivity for multiple applications, including game controllers, PC peripherals, automatic meter reading, security systems, telemetry and point-of-sale vending equipment.

The ML2726 is a highly integrated RF transceiver incorporating a sigma-delta fractional-N synthesizer, voltage controlled oscillator (VCO), upconversion and downconversion mixers, data slicer and transceiver configuration registers. It features a 2Mbps data transmission rate and incorporates self-alignment of the low-IF receiver and phase locked loop (PLL) detection and control, both easing implementation and eliminating the cumbersome mass production tuning process, which is customary with competing transceiver solutions.

Other key specifications of the ML2726 include -81dBm sensitivity at 0.1 percent bit error rate (BER), as well as integrated power regulation enabling 2.7V to 4.5V operation.
