Product Details

PRODUCT DESCRIPTION

The AD8349 is a silicon, monolithic, RF quadrature modulator that is designed for use from 700 MHz to 2700 MHz. Its excellent phase accuracy and amplitude balance enable high performance direct RF modulation for communication systems.
The differential LO input signal is buffered, and then split into an in-phase (I) signal and a quadrature-phase (Q) signal using a polyphase phase splitter. These two LO signals are further buffered and then mixed with the corresponding I channel and Q channel baseband signals in two Gilbert cell mixers. The mixersâ€™ outputs are then summed together in the output amplifier. The output amplifier is designed to drive 50 â„¦ loads.

FEATURES

Output frequency range: 700 MHz to 2700 MHz
Modulation bandwidth: dc to 160 MHz (large signal BW)
1 dB output compression: 5.6 dBm @ 2140 MHz
Output disable function: output below â€“50 dBm in < 50 ns
Noise floor: â€“156 dBm/Hz
Phase quadrature error: 0.3 degrees @ 2140 MHz
Amplitude balance: 0.1 dB
Single supply: 4.75 V to 5.5 V
Pin compatible with AD8345/AD8346s
16-lead, exposed-paddle TSSOP package

APPLICATIONS

Cellular/PCS communication systems infrastructure WCDMA/CDMA2000/PCS/GSM/EDGE
Wireless LAN/wireless local loop
