1.0 GHz Differential Amplifier
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.

At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
AD8350AR20-EVAL is a fully populated, 4-layer, FR4-based evaluation board designed to allow easy evaluation of all features of the AD8350. The board is configured to allow easy evaluation using single-ended 50 Ω test equipment. The input and output transformers have a 4-to-1 impedance ratio and transform AD8350's 200 Ω input and output impedances to 50 Ω.
