Product Details

The AD8369 is a high performance, digitally controlled variable gain amplifier, designed to be used at IF frequencies within cellular receivers.

The device features a 4-bit digitally controlled gain control interface configurable for either parallel or 3 wire serial control. The gain control range spans 45 dB adjustable in 3 dB increments.

The AD8369 is ideally suited to be used in digital IF receivers and is fully specified for operation at common IF frequencies 70 / 140 / 190 / 240 / 380 MHz. The gain stability and flatness is below 0.1 dB over a 20 MHz channel bandwidth at 380 MHz. Coupled with the low distortion and the ability to drive 200 Ω or 1 K Ω, the AD8369 allows optimal placement and flexibility as a high IF gain control element.

The AD8369 is fabricated on an advanced silicon bipolar process, operating on a single 3 or 5 volt supply, packaged in space saving 16-lead thin shrunk small outline (TSSOP) package and fully specified over the –40ºC to +85ºC temperature range.

ADIsimPLL™

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.

ADIsimRF

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.

Design Resources

ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well.  "Zero defects" for shipped products is always our goal.
