Analog Devices Inc. ADL5920-EVALSDPZ

Overview

ADL5920-EVALSDPZ from Analog Devices is a fully populated 4-layer FR4 evaluation board for the ADL5920 bidirectional RF power and return loss detector IC, featuring integrated AD7091R-5 12-bit ADC and SDP connector for USB interface, enabling real-time RF power and return loss measurement in lab and design validation environments.

For engineers reviewing the ADL5920-EVALSDPZ datasheet, ADL5920-EVALSDPZ pinout, ADL5920-EVALSDPZ application, or ADL5920-EVALSDPZ equivalent, this board supports rapid characterization of ADL5920 performance across 9 kHz to 7 GHz with USB-powered operation, on-board ADC sampling, and GUI-driven measurement display-no external supply or instrumentation required.

Technical Context

The ADL5920-EVALSDPZ implements a complete signal chain for RF detector evaluation: it hosts the ADL5920 IC (9 kHz–7 GHz, bidirectional RMS power/return loss detector), pairs it with the AD7091R-5 12-bit, 1 MSPS SAR ADC for analog output digitization, and routes digital data via an SDP (System Development Platform) interface compliant with Analog Devices' standard SDP-S controller board.

No external power is needed-the board draws all operating power (3.3 V and 5 V) from the USB port through the SDP-S controller; RF excitation and load are applied via calibrated 2.92 mm connectors labeled IN and OUT, leveraging the ADL5920's inherent bidirectionality without hardware reconfiguration.

FAQ

What is the ADL5920-EVALSDPZ used for?

The ADL5920-EVALSDPZ is used to evaluate the ADL5920 bidirectional RF power and return loss detector IC. It enables real-time measurement of forward and reflected RF power across 9 kHz to 7 GHz using its on-board AD7091R-5 ADC and SDP interface, supported by a GUI that displays computed power and return loss values directly from USB-connected PCs.

Does the ADL5920-EVALSDPZ require an external power supply?

No, the ADL5920-EVALSDPZ does not require an external power supply. It operates entirely from USB power delivered through the SDP-S controller board. The board derives both 3.3 V and 5 V rails internally, eliminating need for bench supplies or additional regulators during evaluation of the ADL5920-EVALSDPZ.

Which ADC is integrated on the ADL5920-EVALSDPZ?

The ADL5920-EVALSDPZ integrates the AD7091R-5-a 12-bit, 1 MSPS SAR ADC-to digitize the analog output voltages from the ADL5920 detector. This ADC provides sufficient resolution and sampling rate to capture dynamic RF power and return loss measurements for accurate GUI-based analysis on the ADL5920-EVALSDPZ.

Is the ADL5920-EVALSDPZ compatible with standard USB connections?

The ADL5920-EVALSDPZ connects to a PC via USB-but only indirectly. It requires the separate SDP-S controller board, which acts as a USB-to-SDP bridge. The ADL5920-EVALSDPZ itself has an SDP connector, not a native USB port; full USB functionality depends on pairing with the official Analog Devices SDP-S hardware.

Can the ADL5920-EVALSDPZ measure both forward and reflected power simultaneously?

Yes, the ADL5920-EVALSDPZ supports simultaneous forward and reflected power measurement because the ADL5920 IC is fully bidirectional. Its two 2.92 mm connectors (IN and OUT) allow either port to serve as input or load termination, enabling flexible configuration for measuring incident, reflected, or differential RF signals without hardware modification on the ADL5920-EVALSDPZ.
