RF2051 High Performance Wideband RF Synthesizer/VCO with Integrated RF Mixers
The RF2051 is a very 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 oscillators (VCOs) and dividers to produce a low-phase noise LO signal with a very fine frequency resolution. The LO output drives the built-in RF mixers which convert the signal into the required frequency band. The bias current can be programmed to optimize the supply current/performance trade-off. The LO generation blocks have been designed to continuously cover the frequency range from 300MHz to 2400MHz. The RF mixers are very broad band and operate from 100MHz to 2500MHz at the RF ports of the device. An external crystal of between 10MHz and 52MHz or an external reference source of between 10MHz and 104MHz can be used with the RF2051 to accommodate a variety of reference frequency options.The device is programmed using a true three-wire serial interface. The RF2051 is designed for 2.7V to 3.6V operation for compatibility with portable battery powered devices. It is available in a plastic 32-pin 5mmx5mm QFN package.
