AD8349AREZ Description

Short technical summary and product information.

The AD8349AREZ from Analog Devices is a silicon, monolithic RF quadrature modulator operating within a frequency range of 700 MHz to 2700 MHz. It is engineered for high-performance direct RF modulation in communication systems, featuring excellent phase accuracy and amplitude balance.

Key electrical specifications include a modulation bandwidth of DC to 160 MHz (large signal BW), a 1 dB output compression point of 5.6 dBm at 2140 MHz, and a noise floor of -156 dBm/Hz. The device also incorporates an output disable function, allowing the output to fall below -50 dBm in less than 50 ns. It operates from a single supply voltage between 4.75 V and 5.5 V.

This modulator is suitable for applications such as cellular/PCS communication systems infrastructure, WCDMA/CDMA2000/PCS/GSM/EDGE, wireless LAN/wireless local loop, and LMDS/broadband wireless access systems. It is fabricated using Analog Devices’ advanced complementary silicon bipolar process.

The AD8349AREZ is available in a 16-lead, exposed-paddle TSSOP package and is designed for surface mount applications. Its performance is specified over an operating temperature range of -40°C to +85°C.
