Broadband quadrature modulator for 50-2200 MHz

26 July 2006 Analogue, Mixed Signal, LSI

A quadrature modulator IC that operates from 50-2200 MHz, making it well-suited for low intermediate frequency (IF) and RF applications such as broadband wireless access systems, microwave radio link transmitters, cable modem termination systems and cellular infrastructure, is available from Analog Devices. Requiring only a single-ended, two-times local oscillator input, the ADL5385 converts complex modulation information from the baseband to the final RF input, over a broad range of LO frequencies.

According to the company, the ADL5385 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 (-158 dBm/Hz). The -46 dBm carrier feedthrough and -50 dBc sideband suppression at 140 MHz minimises the need for calibration and nulling in complex high-order modulation applications such as 16 QAM and greater.

The ADL5385 accepts wideband inputs from DC to 700 MHz that are compatible with the output levels of the company's AD977x family of TxDAC+ transmit digital-to-analog converters. Its low local oscillator drive requirement of -7 dBm is also compatible with the ADL4360 series of integrated PLL with VCO products.
