Product Details
The AD8347 is a single chip, broadband 2.7GHz quadrature demodulator. The part integrates 65dB linear-in-dB AGC, divided between RF input and at the baseband outputs following the mixers. The In-phase and Quadrature signals are brought out off chip for filtering prior to the final output amplifier stage. The final output amplifiers allow the user to adjust the DC common mode level to provide a direct interface into a dual channel I/Q ADC.
With 65dB linear-in-dB gain control, 50MHz demodulation bandwidth and excellent phase and amplitude balance the AD8347 is ideally suited direct conversion radios in point to point and point to multipoint broadband wireless applications.
The AD8347 is fabricated on an advanced bipolar process, operating on a single 3 or 5 volt supply, packaged in space saving 28 lead thin shrunk small outline (TSSOP) package and fully specified over the -40 to +85 C temperature range.

Tools & Simulations
Design Tools
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.
