RF2052 High Performance Wideband RF Synthesizer/VCO with Integrated RF Mixer

The RF2052 is a very wideband RF frequency conversion chip with integrated local oscillator (LO) generation and an RF mixer. 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 mixer which converts 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 mixer is very broad band and operates 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 RF2052 to accommodate a variety of reference frequency options.The device is programmed using a true three-wire serial interface. The RF2052 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.
