AD8345 140 MHz TO 1000 MHz Quadrature Modulator

Availability Samples part number (AD8345ARE) and an evaluation board, part number (AD8345-EVAL) are available. Other Modulator / Demodulator Products

The AD8345 is a silicon RFIC quadrature modulator, designed for use from 140 MHz to 1000 MHz. The part provides a very low noise floor and high output power supporting a significant improvement in output dynamic range. The AD8345 needs a low LO drive level and provides a fully specified 50 Ω buffered output.

The part provides excellent amplitude and phase balance and sideband suppression specifications to enable higher order/capacity QAM modulated radios.

Additionally the AD8345 has been tested and supports the requirements as an IF modulator within CDMA/GSM/W-CDMA cellular infrastructure equipment and as a direct conversion modulator for the 800 – 900 MHz cellular bands.

The AD8345 is supplied in 16-lead Thin Shrunk Small Outline (TSSOP) package with exposed paddle, and fully specified over –40°C to +85°C temperature range.
