Product Description
The RF2052 is a low power, high performance, wideband RF frequency conversion chip with integrated local oscillator (LO) generation and 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 buffered LO output drives the built-in RF mixer which converts the signal into the required frequency band. The mixer bias current can be programmed dependent on the r...
