RF Frequency and Power Measurement

ADI’s portfolio of logarithmic and RMS-DC-based RF detectors enable low-cost measurement of sine-waves and complex waveforms from low frequency to millimeter wave frequencies. Coupled with our ADCs and embedded processors, these devices enable RF frequency and power measurement solutions from bench instrumentation to handheld and field instruments. In addition, ADI offers a family of ARM Cortex M3-based single-chip solutions incorporating high resolution ADCs suitable for a variety of handheld and portable applications.

Evaluation Kits

The AD9689-2600EBZ supports the AD9689-2600, a 14-bit, 2.6GSPS dual analog-to-digital converter (ADC). The device has an on-chip buffer and a sample-and-hold circuit designed for low power, small size, and ease of use. This device is designed support direct RF sampling analog signals of up to 5 GHz. The 3 dB bandwidth of the ADC input is greater than 9 GHz. The AD9689 is optimized for wide input bandwidth, high sampling rate, excellent linearity, and low power in a small package.


This reference design provides all of the support circuitry required to operate the ADC in its various modes and configurations. It is designed to interface directly with the ADS7-V2EBZ data capture card, allowing users to download captured data for analysis. The device control and subsequent data analyses can now be done using the ACE software package.
