ADI AD8361-EVALZ 100MHz To 2.5GHz AD8361 TruPwr™ Power Detector Evaluation Board

Shenzhen Mingjiada Electronics Co., Ltd., as a professional electronic component supplier, provides the ADI AD8361-EVALZ evaluation board to its extensive clientele. This evaluation board is specifically designed for the AD8361 TruPwr™ RF power detector, serving as an ideal tool for high-frequency circuit design and RF applications.

【AD8361-EVALZ Product Overview】

The AD8361-EVALZ is a fully assembled and tested 4-layer FR4 evaluation board for rapid evaluation and development of the AD8361 ARMZ RF power detector. The board integrates all necessary peripheral circuitry, requiring only power and signal source connections for operation, significantly simplifying the prototyping phase.

This AD8361-EVALZ evaluation board is tailored for RF power detection applications spanning 100MHz to 2.5GHz. It accurately measures the true power of both simple and complex modulated waveforms, making it particularly suitable for measuring high crest factor signals in modern wireless communication systems.

【AD8361-EVALZ Core Features】

Wide Frequency Range: Supports operating frequencies from 100MHz to 2.5GHz, covering most RF application bands.

Simple Power Requirements: Requires only a single power supply of 2.7V to 5.5V, with current consumption approximately 15mA.

Moderate Input Range: Input power range approximately -21 dBm to 5 dBm (based on AD8361 chip specifications).

Comprehensive Interfaces: On-board edge-mounted SMA connectors, including RF input (RFIN) and RMS output (VRMS) interfaces.

High-Precision Measurement: The AD8361 chip maintains ±0.25 dB linear response up to 2.5 GHz.

【AD8361-EVALZ Evaluation Board Usage】

Power Connection: Connect a 2.7V to 5V, 15mA power supply to the vector pins labelled VPOS and GND.

Signal Input: RF input signals are connected via the edge-mounted SMA connector (RFIN).

Signal Output: RMS output signals are obtained via the edge-mounted SMA connector (VRMS).

Measurement and Debugging: Connect appropriate test equipment for signal observation and analysis.

【AD8361-EVALZ Technical Advantages】

The AD8361-EVALZ employs proprietary TruPwr™ technology to precisely measure the RMS power of various complex modulated signals, unaffected by variations in the waveform's peak-to-average power ratio. It integrates a broadband logarithmic amplifier and envelope detector internally, along with temperature compensation circuitry, ensuring stable measurement accuracy across diverse environmental conditions.

The AD8361-EVALZ offers three operating modes to flexibly accommodate different ADC requirements: Ground Reference Mode (origin at zero), Internal Reference Mode (output offset to 350mV above ground level), and Power Supply Reference Mode (output offset to VS/7.5).

【AD8361-EVALZ Application Areas】

Communications System Testing

Complex Modulation Signal Measurement: The AD8361-EVALZ is particularly suited for measuring complex modulated waveforms with high peak-to-RMS ratios, such as CDMA, W-CDMA, and QAM.

RF Power Monitoring: For precise power measurement in RF transmitters or receivers.
