The AD8350 series are high performance fully-differential amplifiers useful in RF and IF circuits up to 1000 MHz. The amplifier has excellent noise figure of 5.9 dB at 250 MHz. It offers a high output third order intercept (OIP3) of +28 dBm at 250 MHz. Gain versions of 15 dB and 20 dB are offered.
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 driver, and high speed data interface driver, among other functions. The AD8350 input can also be used as a single-ended-to-differential converter.
The amplifier can be operated down to 5 V with an OIP3 of +28 dBm at 250 MHz and slightly reduced distortion performance. The wide bandwidth, high dynamic range and temperature stability make this product ideal for the various RF and IF frequencies required in cellular, CATV, broadband, instrumentation and other applications.
The AD8350 is offered in an 8-lead single SOIC package and μSOIC package. It operates from 5 V and 10 V power supplies, drawing 28 mA typical. The AD8350 offers a power enable function for power-sensitive applications. The AD8350 is fabricated using Analog Devices’ proprietary high speed complementary bipolar process. The device is available in the industrial (–40°C to +85°C) temperature range.

Evaluation Kits (1)
AD8350AR15-EVAL is a 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.
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.
Tools & Simulations
Sys-Parameter models contain behavioral parameters, such as P1dB, IP3, gain, noise figure and return loss, which describe nonlinear and linear characteristics of a device.
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.
