AD8350:  1.0 GHz Differential Amplifier

Product Details


TheAD8350 Series is composed of a family of high-performance, fully-differential amplifiers useful in RF and IF circuits up to 1200 MHz. The AD8350 has an excellent noise figure of 4.9 dB at 250 MHz and offers a high output third order intercept (OIP3) of +34dBm at 250 MHz. Gain versions of 15 and 20 dB are also offered. IM3 distortion is -67dBc at 250 MHz. OIP3 and IMD performance improves at frequencies below 250 MHz.

The AD8350 is designed to meet the demanding performance requirements of communications transceiver applications. It enables a high dynamic range differential signal chain with exceptional linearity and increased common-mode rejection. The device can be used as a general purpose gain block, an A-to-D buffer, and high speed data interface driver among other functions. The AD8350 input can also be used in a single-ended mode, providing a low distortion single-ended to differential conversion.

Two versions of the evaluation board are available for this product and may be ordered using the following product numbers: AD8350AR15-EVAL and AD8350AR20-EVAL. Schematic and layout for this evaluation board is contained in the product datasheet.
