RF2059 High Performance RF PLL/VCO With RF Mixers For WLAN Band-Shifters
The RF2059 is a low power, high performance, wideband RF frequency conversion chip with integrated local oscillator (LO) generation and a pair of RF mixers. The RF synthesizer includes an integrated fractional-N phase locked loop with voltage controlled oscillator (VCO) and dividers to produce a low-phase noise LO signal with a very fine frequency resolution. The buffered LO output drives the built-in RF mixers which convert the signal into the required frequency band. The mixer bias current can be programmed dependent on the required performance and available supply current. The VCO has been designed to cover the frequency range from 1550MHz to 2050MHz. The LO dividers can be selected to divide the VCO output frequency by two or four to give lower LO frequencies. The RF mixers are very broad band and operate from 30 MHz to 2500 MHz at the input and output, enabling both up and down conversion. An external crystal of between 10MHz and 52MHz or an external reference source of between 10MHz and 104MHz can be used with the RF2059 to accommodate a variety of reference frequency options.The high level of integration makes the RF2059 ideal for WLAN band shifting applications, offering a low cost and compact single chip solution. All on-chip registers are controlled through a simple three-wire serial interface. The RF2059 is designed for 2.7V to 3.6V operation for compatibility with portable, battery powered devices. It is available in a plastic 32-pin, 5mm x 5mm QFN package.
