Product Summary

The RF2051SB is a low power, high performance, wideband RF frequency conversion chip with integrated local oscillator (LO) generation and a pair of RF mixers. The RF2051SB 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 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 applications of the RF2051SB include CATV Head-Ends, Digital TV Up/Down Converters, Digital TV Repeaters, Multi-Dwelling Units, Cellular Repeaters, Frequency Band Shifters, UHF/VHF Radios, Diversity Receivers, Software Defined Radios, Satellite Communications, Super-Heterodyne Radios.
