Product Details
The AD8370 is a high performance, digitally controlled variable gain amplifier, designed to be used at IF frequencies within communication infrastructure equipment.
The part provides two gain control ranges that are controlled through a three wire digital interface, and allow the user to attain fine gain control for maximum receiver sensitivity.
The AD8370 has been fully specified for operation at common wireless IF frequencies 70 / 140 / 190 / 240 / 380MHz. The high output compression and fine gain control adjustability makes the AD8370 an ideal choice for to be used within digital receiver AGC circuits for GSM / CDMA2000 / W-CDMA cellular base stations.
The AD8370 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 –40 to +85 C temperature range.
Availability
Samples AD8370ARU and an evaluation boards AD8370-EVAL are available.

Design Tools
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.
