Additional Details

The ADRF6703 provides a quadrature modulator and synthesizer solution within a small 6 mm × 6 mm footprint while requiring minimal external components.

The ADRF6703 is designed for RF outputs from 1550 MHz to 2650 MHz. The low phase noise VCO and high performance quadrature modulator make the ADRF6703 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× f_LO 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 ADRF6703 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.

Product Detail

ADRF6703-EVALZ is a fully-populated, 4-layer, Rogers 4350-based evaluation board. A 5 V/300 mA power supply is required and should be connected to the test points labeled VCC and GND (red and black). The PLL reference should be connected to the SMA connector labeled REF_IN, the baseband inputs to the SMA connectors labeled IPBB, INBB, QPBB, and QNBB. The RF output is available on the SMA labeled RF OUT. The evaluation board can be programmed through the USB port of a PC running Windows XP or Vista with Microsoft .NET Framework 3.5 installed. The required control software can be downloaded from www.analog.com.
