Analog Devices: EVAL-ADRF6755SDZ Evaluation Board for the ADRF6755 I/Q Modulator with Integrated Fractional-N PLL and VCO

Kit Overview

The Analog Devices EVAL-ADRF6755SDZEVAL-ADRF6755SDZ evaluation board is designed to allow the user to evaluate the performance of the ADRF6755ADRF6755 100 MHz to 2400 MHz I/Q Modulator with Integrated Fractional-N PLL and VCO.

It contains the I/Q modulator with integrated fractional-N PLL and VCO, Connector to interface to a standard USB interface board (SPD-S) that must be ordered with the EVAL-ADRF6755SDZEVAL-ADRF6755SDZ board, DC biasing and filter circuitry for the baseband inputs, Low-pass loop filter circuitry, An 80 MHz reference clock, Circuitry to monitor the LOMON outputs, SMA connectors for power supplies and the RF output, The evaluation board is supplied with the associated driver software to allow easy programming of the ADRF6755ADRF6755.

The SPI interface is provided by an additional SPD-S controller board (EVAL-SDP-CB1ZEVAL-SDP-CB1Z). This must be ordered with the ADRF6755ADRF6755 evaluation board. The system demonstration platform (SDP) is a hardware and software platform that provides a means to communicate from the PC to Analog Devices products and systems that require digital control and/or readback. The SPD-S controller board connects to the PC via USB 2.0 and to the ADRF6755ADRF6755 evaluation board via a small footprint, 120-pin connector.

The ADRF6755ADRF6755 is a highly integrated quadrature modulator, frequency synthesizer, and programmable attenuator. The device covers an operating frequency range from 100 MHz to 2400 MHz for use in satellite, cellular, and broadband communications.

The ADRF6755ADRF6755 modulator includes a high modulus, fractional-N frequency synthesizer with integrated VCO, providing less than 1 Hz frequency resolution, and a 47 dB digitally controlled output attenuator with 1 dB steps.

Key Applications: satellite, cellular, and broadband communications
