Analog Devices Inc. ADRF5024-EVALZ

Overview

ADRF5024-EVALZ from Analog Devices is a 4-layer RF evaluation board designed to characterize the ADRF5024 silicon SPDT reflective switch (100 MHz–44 GHz) under real-world PCB conditions. It features Rogers RO4003 dielectric (8 mil top layer), coplanar waveguide transmission lines (50 Ω), 2.4 mm end-launch connectors for RFC/RF1/RF2, and dual layout options-impedance-matched and non-matched-for accurate de-embedding of board loss using THRU CAL calibration.

For engineers reviewing the ADRF5024-EVALZ datasheet, ADRF5024-EVALZ pinout, ADRF5024-EVALZ application, or ADRF5024-EVALZ equivalent, this board enables precise measurement of insertion loss (1.0 dB typ. to 18 GHz), isolation (≥35 dB to 44 GHz), RF settling time (17 ns), P1dB (27.5 dBm), and hot-switching capability (27 dBm) in mmWave test setups, 5G infrastructure validation, and radar front-end prototyping.

Technical Context

The ADRF5024-EVALZ implements two parallel RF layouts on a single 62-mil-thick PCB: one with integrated 5-mil impedance-matching stubs at each RF port (RFC, RF1, RF2), and one without-enabling direct comparison of embedded vs. de-embedded device performance. The top layer carries all RF and DC traces; inner and bottom layers are solid ground planes optimized for RF return path integrity and thermal dissipation.

It supports full characterization of the ADRF5024's CMOS/LVTTL-compatible CTRL interface (0 V / 3.3 V logic), dual-supply operation (+3.3 V / −3.3 V), and high-power handling (27 dBm through path, 27 dBm hot switching) across −40°C to +105°C. THRU CAL line (J6–J7 or J4–J5) provides reference path for vector network analyzer (VNA) calibration to isolate IC-level S-parameters from PCB parasitics.

FAQ

What is the primary purpose of the ADRF5024-EVALZ?

The ADRF5024-EVALZ is a dedicated evaluation board for the ADRF5024 ultrawideband SPDT switch. Its purpose is to enable accurate, repeatable RF characterization-including insertion loss, isolation, and switching speed-by providing calibrated 2.4 mm launchers, controlled-impedance CPWG traces, and THRU CAL reference paths that allow de-embedding of PCB effects from measured S-parameters.

Does the ADRF5024-EVALZ include the ADRF5024 IC?

Yes, the ADRF5024-EVALZ includes one populated ADRF5024BCCZN silicon SPDT switch (12-terminal LGA package) as U2 on the board. The evaluation board is shipped fully assembled with the IC, bypass capacitors (C8/C9), test points, and 2.4 mm RF launchers pre-installed per Analog Devices' official design.

How does the THRU CAL function on the ADRF5024-EVALZ?

The THRU CAL line on the ADRF5024-EVALZ (J6–J7 or J4–J5) is a direct 50 Ω transmission path used for vector network analyzer calibration. By measuring its S21 response, users can mathematically de-embed board loss from ADRF5024 measurements-yielding true device-level insertion loss, return loss, and isolation data referenced directly to the IC pins.

Can the ADRF5024-EVALZ be used for hot-switching validation?

Yes, the ADRF5024-EVALZ supports hot-switching validation up to 27 dBm RF input power at 200 MHz–40 GHz, matching the ADRF5024's specified hot-switching rating. Its robust grounding, low-inductance supply paths (with 100 pF bypass caps), and thermally optimized layout ensure stable operation during dynamic RF path switching under full RF load.

What RF frequency range can be accurately evaluated using the ADRF5024-EVALZ?

The ADRF5024-EVALZ supports accurate evaluation of the ADRF5024 from 100 MHz to 44 GHz. Its Rogers RO4003 top dielectric, 2.4 mm end-launch connectors, and 50 Ω CPWG traces maintain phase stability and minimal dispersion across this full band-validated by Analog Devices' published insertion loss curves (e.g., 1.0 dB typ. to 18 GHz, 1.7 dB typ. to 44 GHz).
