Analog Devices Inc. ADL5802-EVALZ

Overview

ADL5802-EVALZ from Analog Devices is an evaluation board for the ADL5802 dual-channel, high-linearity active mixer IC, supporting RF/LO frequency ranges from 100 MHz to 6 GHz and enabling downconversion with up to 28 dBm input IP3 and 11 dB SSB noise figure. It provides full access to all 24 pins of the 4 mm × 4 mm LFCSP package and integrates optimized broadband baluns (TC1-1-13M+, TC4-1W+) for RF, LO, and IF interfaces.

For engineers reviewing the ADL5802-EVALZ datasheet, ADL5802-EVALZ pinout, ADL5802-EVALZ application, or ADL5802-EVALZ equivalent, this board supports rapid characterization of mixer performance-including gain flatness, IP3 vs. VSET, LO leakage, and channel isolation-across cellular, microwave radio link, and diversity receiver designs under real-world bias and matching conditions.

Technical Context

The ADL5802-EVALZ implements a complete, calibrated test platform for the ADL5802 IC, featuring differential RF1/RF2, LOIN/LOIP, and OP1/OP2 interfaces with 50 Ω SMA connectors, on-board choke inductors for VPOS and biasing, and resistor-programmable VSET control. It supports both low-side and high-side LO injection configurations.

Designed per Analog Devices' reference layout guidelines, the board uses controlled-impedance microstrip routing, grounded exposed paddle soldering, and thermal vias to maintain signal integrity and thermal stability across −40°C to +85°C operation-enabling accurate measurement of dynamic parameters like input P1dB (12–13 dBm), IF output impedance (~200 Ω), and RF-to-IF isolation (>25 dBc).

FAQ

What is the primary function of the ADL5802-EVALZ?

The ADL5802-EVALZ is an evaluation board purpose-built to characterize the ADL5802 dual-channel active mixer IC. It provides full access to all 24 pins, integrated baluns, bias circuitry, and SMA connectors-enabling engineers to measure key RF performance metrics including power conversion gain, input IP3, SSB noise figure, LO leakage, and channel isolation across 100 MHz–6 GHz.

Does the ADL5802-EVALZ support both RF channels simultaneously?

Yes, the ADL5802-EVALZ fully supports concurrent operation of both RF1 and RF2 channels on the ADL5802 IC. Its layout includes separate differential RF input paths (RF1+/− and RF2+/−), independent IF output transformers, and shared LO distribution-allowing simultaneous two-channel downconversion testing with measured RFI1-to-RFI2 isolation exceeding 33 dBc at 3.5 GHz.

What baluns are included on the ADL5802-EVALZ board?

The ADL5802-EVALZ ships with three sets of optimized baluns: TC1-1-13M+ for 900/1900 MHz RF/LO, 2500BL14M050 for 2.5 GHz, 3600BL14M050 for 3.5 GHz, and 5400BL15B050 for 5.5 GHz operation-each selected to match the ADL5802's wideband port impedances and minimize return loss (<−18 dB) across their respective bands.

Can the ADL5802-EVALZ be used for high-side LO injection?

Yes, the ADL5802-EVALZ supports both low-side and high-side LO injection configurations. The board's differential LO path (LOIN/LOIP) and flexible IF termination options allow users to configure the ADL5802 for either mode-verified in the datasheet's "Downconverter Mode Using a Broadband Balun" and "Performance Up to 8 GHz" sections.

Is the ADL5802-EVALZ compatible with standard lab equipment?

Yes, the ADL5802-EVALZ features industry-standard 50 Ω SMA connectors on all RF, LO, and IF ports-ensuring direct compatibility with vector network analyzers, spectrum analyzers, signal generators, and power meters. All DC supply and control signals (VSET, ENBL) are accessible via screw terminals or test points for seamless integration into automated test setups.
