RF2054 Datasheet LOW POWER PLL AND VCO

Manufacturer: RF Micro Devices (now Qorvo)

General Description

The RF2054 is a low power, 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.
