    Qorvo's RF2054 is a 2.2V, high performance, frequency conversion chip with integrated local oscillator (LO) and a pair of RF mixers. The synthesizer includes an integrated fractional-N phase locked loop that can control the VCO to produce a low phase noise and low spurious LO signal with very fine frequency resolution. The VCO output can then be divided by one, two, or four in the LO divider, the output of which drives the mixer, which converts the signal into the required frequency band. The LO generation block has been optimized to operate with the VCO covering the frequency range from 940MHz to 1000MHz, set by the value of the external inductor used. The mixers are broadband and can operate from 30MHz to 2500MHz at the input and output, enabling both up and down conversion. An external reference source of between 10MHz and 26MHz can be used with the RF2054. All on-chip registers are controlled through a simple three-wire serial interface. The RF2054 has been characterized for 2.2V operation and low power consumption. It is available in a plastic 32-pin, 5mm x 5mm QFN package.
