RF Micro Devices DK2053
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.| Part No. | DK2053 |
