Analog Devices Inc. ADL5511-EVALZ

Overview

ADL5511-EVALZ from Analog Devices is a dedicated evaluation board for the ADL5511 true RMS and envelope detector IC, enabling rapid characterization of RF signal power and envelope dynamics in 50 Ω systems. It supports single 4.75 V to 5.25 V supply operation, features broadband 50 Ω RF input matching via R5, and provides accessible VRMS (clip or SMA), VENV (SMA), and EREF (clip) outputs for real-time measurement.

For engineers reviewing the ADL5511-EVALZ datasheet, ADL5511-EVALZ pinout, ADL5511-EVALZ application, or ADL5511-EVALZ equivalent, this board delivers validated signal path integrity, configurable filtering (FLT1–FLT4), switch-controlled device enable/disable, and FET-probe-ready VENV access-critical for high-fidelity RF envelope analysis and RMS validation workflows.

Technical Context

The ADL5511-EVALZ implements a 4-layer PCB layout optimized for minimal parasitic coupling between RF input, RMS output, and envelope output paths. It integrates discrete decoupling (C13 = 100 pF, C14 = 0.1 μF), configurable filter augmentation points (C2, C6, C10, C17), and selectable interface options including P2 edge connector access to all ADL5511 signals.

Power delivery uses vector pins VPOS/GND with on-board 0 Ω jumpers (R1, R18, R19, R20) and open-circuit default positions for C7–C10, C9, and JP1-enabling precise control over output filtering, carrier-removal bandwidth, and probe loading. The board supports both clip-lead and SMA-based signal extraction without soldering by default.

FAQ

What is the primary function of the ADL5511-EVALZ?

The ADL5511-EVALZ is an evaluation board built exclusively to characterize the ADL5511 true RMS and envelope detector IC. It provides calibrated signal paths, configurable filtering, and multiple output access methods-including clip leads and SMA connectors-to validate RF power measurement accuracy, envelope response time, and dynamic range under real-world bias and load conditions.

Does the ADL5511-EVALZ require external power supplies or additional hardware to operate?

No. The ADL5511-EVALZ operates from a single 4.75 V to 5.25 V DC supply applied to its VPOS and GND vector pins. All necessary decoupling, matching, and output conditioning components are populated per UG-312 Rev. 0 defaults. No external hardware is required to evaluate basic ADL5511 functionality, though SMA cables, oscilloscopes, and RF sources are needed for signal injection and measurement.

How is RF input matching implemented on the ADL5511-EVALZ?

The ADL5511-EVALZ achieves broadband 50 Ω RF input matching using a single 75 Ω surface-mount resistor (R5) in series with the ADL5511's internal input impedance. This passive network eliminates the need for external baluns or matching networks while maintaining consistent return loss across the ADL5511's specified frequency range.

Can the ADL5511-EVALZ be used to measure both RMS and envelope outputs simultaneously?

Yes. The ADL5511-EVALZ provides independent, low-interference access to both VRMS (via clip point or VRMS1 SMA) and VENV (via VENV SMA) outputs. Layout isolation, separate decoupling, and configurable filtering (e.g., FLT4 for RMS averaging, FLT2/FLT3 for envelope carrier removal) allow concurrent acquisition without cross-talk degradation in typical lab setups.

Is the ADL5511-EVALZ RoHS compliant and ESD-safe for bench use?

Yes. The ADL5511-EVALZ conforms to RoHS Directive requirements as shipped, and its design incorporates ESD-aware layout practices. However, it is labeled ESD-sensitive per UG-312: users must observe proper grounding, avoid uncontrolled static discharge, and refrain from touching exposed pads or connectors without wrist straps-especially before powering the ADL5511-EVALZ or connecting instruments.
