GENERAL DESCRIPTION

The ADRF6702 provides a quadrature modulator and

synthesizer solution within a small 6 mm × 6 mm footprint

while requiring minimal external components.

The ADRF6702 is designed for RF outputs from 1200 MHz to

2400 MHz. The low phase noise VCO and high performance

quadrature modulator make the ADRF6702 suitable for next

generation communication systems requiring high signal

dynamic range and linearity. The integration of the IQ

modulator, PLL, and VCO provides for significant board

savings and reduces the BOM and design complexity.

The integrated fractional-N PLL/synthesizer generates a 2× fLO

input to the IQ modulator. The phase detector together with an

external loop filter is used to control the VCO output. The VCO

output is applied to a quadrature divider. To reduce spurious

components, a sigma-delta (Σ-Δ) modulator controls the

programmable PLL divider.

The IQ modulator has wideband differential I and Q inputs,

which support baseband as well as complex IF architectures.

The single-ended modulator output is designed to drive a

50 Ω load impedance and can be disabled.

The ADRF6702 is fabricated using an advanced silicon-

germanium BiCMOS process. It is available in a 40-lead,

exposed-paddle, Pb-free, 6 mm × 6 mm LFCSP package.

Performance is specified from −40°C to +85°C. A lead-free

evaluation board is available.
