RFMD RF2053
The RF2053 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 that can control an external VCO to produce a low-phase noise LO signal with a very fine frequency resolution. The VCO output frequency can be divided by 1, 2, or 4 in the LO divider, whose output is buffered and drives the built-in RF mixer which converts the signal into the required frequency band.| Part No. | RF2053 |
