GENERAL DESCRIPTION
The ADRF6604 is a high dynamic range active mixer with an
integrated fractional-N phase-locked loop (PLL) and a voltage-
controlled oscillator (VCO) for internal mixer LO generation.
Along with the ADRF6601, ADRF6602, and ADRF6603, the
ADRF6604 forms a family of integrated PLL/mixers. The
ADRF6604 covers the frequency range of 2500 MHz to 2900 MHz.

The PLL reference input can support 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

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 the single-ended 50 Ω RF input to
a 200 Ω differential IF output. The IF output can operate up
to 500 MHz.
The ADRF6604 is fabricated using an advanced silicon-germanium
BiCMOS process. It is available in a 40-lead, RoHS-compliant,
6 mm × 6 mm LFCSP with an exposed paddle. Performance is
specified over the −40°C to +85°C temperature range.

... ADRF6604 LO SELECTION LOGIC The downconverting mixer in the ADRF6604 can be used without the internal PLL by applying an external differential LO to Pin 37 (LON) and Pin 38 (LOP). In addition, when using an LO generated by the internal PLL, the LO signal can be accessed directly at these same pins. This function can be used for debugging purposes, or the internally generated LO can be used as the LO for a separate mixer ...
