ADI AD8363-EVALZ 50Hz To 6GHz 50dB TruPwr™ RF Power Detector Evaluation Board

Shenzhen Mingjiada Electronics Co., Ltd., as a globally renowned distributor of electronic components, supplies the ADI AD8363-EVALZ evaluation board—a 50dB TruPwr™ RF power detector specifically designed for high-frequency applications spanning 50Hz to 6GHz.

This AD8363-EVALZ evaluation board, based on the AD8363 TruPwr™ RMS detector chip, enables precise measurement of true RMS power across complex modulated signals, providing robust support for wireless communication system design and testing.

【AD8363-EVALZ Product Overview】

The AD8363-EVALZ is a fully assembled, RoHS-compliant evaluation board specifically designed for assessing and testing the AD8363 TruPwr™ power detector.

This AD8363-EVALZ evaluation system primarily demonstrates the performance characteristics of the AD8363 chip, enabling engineers to rapidly validate its RF power detection capabilities in real-world environments.

As a professional evaluation tool, the AD8363-EVALZ significantly lowers the entry barrier for RF circuit design and shortens product development cycles.

At the core of the AD8363-EVALZ evaluation board is the AD8363 power detector, a true RMS response power detector that can be directly driven by a single-ended 50Ω source.

This feature enables the AD8363 to operate up to 6 GHz without requiring baluns or any form of external input tuning, offering broad frequency applicability.

【Technical Characteristics of the AD8363 Chip】

The AD8363 chip is a true RMS response power detector capable of determining the actual power of high-frequency signals with complex low-frequency modulated envelopes. It may also function as a simple low-frequency RMS voltmeter.

Exceptional RF Performance

The AD8363 delivers over 50 dB dynamic range across an input span from -50 dBm to 0 dBm, maintaining stable operation throughout an exceptionally broad frequency range of 50 Hz to 6 GHz.

Its output is linearly scaled in decibels at 52 mV/dB (approximately 1 V per decade), though alternative slopes can be readily configured.

In terms of precision, the AD8363 excels: logarithmic consistency error is less than ±0.15 dB, temperature stability is less than ±0.5 dB, and accuracy is within ±0.5 dB across the entire dynamic range.

This high precision enables it to handle the large peak-to-average power ratios required for accurate measurement of signals exceeding WiMAX, CDMA, W-CDMA, TD-SCDMA, multi-carrier GSM, and LTE.

Flexible Power Management

The AD8363 operates within a 4.5 V to 5.5 V supply range, with a nominal operating current of 60 mA (at 25°C).

When a logic high is applied to the TCM2/PWDN pin, the chip enters a power-saving mode consuming merely 1.5 mW. It rapidly resumes normal operation within approximately 30 μs, making it highly suitable for low-power applications.

【AD8363-EVALZ Evaluation Board Core Advantages and Performance Parameters】

Wide Frequency Range: Covers 50Hz to 6GHz, suitable for diverse applications spanning low-frequency to microwave bands

High Dynamic Range: Single-ended input dynamic range exceeds 50dB, with input sensitivity ranging from -50dBm to 0dBm

Precise Measurement Capability: Logarithmic output consistency error <±0.15dB, temperature stability <±0.5dB

Simplified Circuit Design: No external balun or input tuning required; directly drives single-ended 50Ω sources

【AD8363-EVALZ Primary Application Scenarios】

Within wireless communications infrastructure, the AD8363-EVALZ is suitable for multi-standard, multi-carrier wireless infrastructure (e.g., MCGSM, CDMA, WCDMA, TD-SCDMA, WiMAX, LTE).

The AD8363-EVALZ is particularly well-suited for next-generation RF applications employing composite signals with highly variable peak-to-average power ratios.

For RF power control, this evaluation board can be employed in power amplifier linearisation/control loops. Precise power amplifier control significantly reduces costs and enhances efficiency.

The AD8363-EVALZ also excels in transmitter power control and transmit signal strength indication (TSSI).

For test and measurement applications, the AD8363-EVALZ evaluation board is an ideal choice for RF instrumentation, delivering precise power measurements suitable for diverse high-frequency communications and instrumentation systems, unaffected by waveform characteristics.

【AD8363-EVALZ Evaluation Board Technical Details】

The AD8363 chip on the AD8363-EVALZ evaluation board is housed in a 4mm × 4mm 16-pin LFCSP package, operating within a voltage range of 4.5V to 5.5V and drawing approximately 60mA.

When a logic high is applied to the TCM2/PWDN pin, the chip's power consumption can be reduced to 1.5mW, with normal operation resuming within approximately 30μs.

The AD8363-EVALZ evaluation board provides a fully assembled, RoHS-compliant solution, enabling engineers to rapidly undertake prototyping and technical validation.

【How to Use the AD8363-EVALZ Evaluation Board】

Employing the AD8363-EVALZ evaluation board for RF power measurement constitutes a relatively straightforward process.

The evaluation board typically connects RF input signals via SMA connectors, whilst requiring a single 5V power supply.

The output signal can be measured via the VOUT pin. When employed as a power measurement device, VOUT is typically connected to VSET.

The output is proportional to the logarithm of the input's root mean square (RMS) value, yielding direct readings in decibels (dB) scaled at 52 mV/dB.

Adding a capacitor to its CHPF pin reduces the high-pass cutoff frequency generated by its internal offset cancellation loop, offering flexibility for diverse applications.
