AD8349AREZ

The AD8349AREZ from Analog Devices is a silicon, monolithic RF quadrature modulator suitable for applications operating between 700 MHz and 2700 MHz. Its design emphasizes excellent phase accuracy and amplitude balance, making it ideal for high-performance direct RF modulation in communication systems.

Key electrical specifications include an output frequency range of 700 MHz to 2.7 GHz, a modulation bandwidth of up to 160 MHz, and a noise floor of -156 dBm/Hz. The device operates on a single supply voltage ranging from 4.75 V to 5.5 V, with a typical current consumption of 150 mA. It features a 1 dB output compression point of -5.6 dBm at 2140 MHz and an output power of -5.1 dBm.

The modulator includes an output disable function, allowing the output to fall below -50 dBm in less than 50 ns. It exhibits a phase quadrature error of 0.3 degrees and an amplitude balance of 0.1 dB at 2140 MHz.

Packaged in a 16-lead, exposed-paddle TSSOP, the AD8349AREZ is designed for surface mount applications. Its performance is specified over a temperature range of -40°C to +85°C.
