Analog Devices’ Broadband Quadrature Modulator Is Industry’s First to Integrate Automatic Gain Control : – ADI’s ADL5386 provides a complete solution for cable and wireless infrastructure applications.

NORWOOD, Mass. (PRWEB) October 28, 2008

Operating over a 50-MHz to 2200-MHz frequency range, the ADL5386 supports high-data-rate complex modulation for next-generation communication infrastructure equipment. Functionally complete, the ADL5386 integrates a 25-dB dynamic range output power detector and a VVA (voltage variable attenuator). Together, they form a closed-loop automatic level control (ALC) or AGC, enabling the ADL5386 to accurately set the output power to a user determined level. The ADL5386 provides a complete subsystem within a small footprint, saving considerable board space, component cost, and circuit complexity over discrete implementations.


ADL5386 Eases Broadband High-Data-Rate Next-Generation Radio Applications


The ADL5386 provides exceptional output dynamic range due to its high output power capability (+10 dBm P1dB), high single-ended output linearity (+24 dBm IP3), and low noise floor (160 dBm/Hz). The 38 dBm carrier feedthrough and 46 dBc sideband suppression at 350 MHz minimizes the need for calibration and nulling in complex high-order modulation applications such as 64 QAM (quadrature amplitude modulation) and greater.


The ADL5386 wideband inputs (dc to 700 MHz) are compatible with the output levels of ADI’s AD977x family of TxDAC+
