2100 MHz to 2600 MHz Rx Mixer ADRF660

The ADRF6603 is a high dynamic range active mixer with an integrated fractional-N phase-locked loop (PLL) and voltage controlled oscillator (VCO) for internal mixer LO generation.

The ADRF6603, together with the ADRF6602, forms a family of integrated PLL/mixers that cover the 2100 MHz to 2600 MHz frequency range.

The PLL reference input supports input frequencies from 12 MHz to 160 MHz. The PFD output controls a charge pump whose output drives an off-chip loop filter.

The loop filter output is then applied to an integrated VCO. The VCO output (2× fLO) is applied to an LO divider and a programmable PLL divider. The programmable PLL divider is controlled by a Σ-Δ modulator (SDM). The modulus of the SDM can be programmed from 1 to 2047.

The active mixer converts a single-ended 50 Ω RF input to a 200 Ω differential IF output. The IF output operates up to 500 MHz.

Fabricated in an advanced silicon-germanium BiCMOS process, the ADRF6603 is available in a 40-lead, exposed pad, 6 mm × 6 mm, RoHS-compliant LFCSP package and is specified over the −40°C to +85°C temperature range.
