Hot-selling and scarce ADRF6655ACPZ-R7 RF Mixer IC General Purpose Up/Down Converter 40-LFCSP-VQ LFCSP40 spot stock

Product Descriptions

The ADRF6655 is a high dynamic range active mixer with integrated PLL and VCO. The synthesizer uses a programmable integer-N/fractional-N PLL to generate a local oscillator input to the mixer.The PLL reference input is nominally 20 MHz.The reference input can be divided by or multiplied by and then applied to the PLL phase detector. The PLL can support input reference frequencies from 10 MHz to 160 MHz. The phase detector output controls a charge pump whose output is integrated in an off-chip loop filter.The loop filter output is then applied to an integrated VCO.The VCO output at 2 ×fLO is then applied to a local oscillator (LO)divider as well as to a programmable PLL divider.

The programmable divider is controlled by an Σ-Δ modulator(SDM). The modulus of the SDM can be programmed between1 and 2047.
