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.
