Analog Devices Inc. ADRF5045-EVALZ

Overview

ADRF5045-EVALZ from Analog Devices is an evaluation board designed to characterize the ADRF5045 9 kHz–30 GHz silicon SP4T RF switch in real-world high-frequency systems. It supports full RF performance validation-including insertion loss (2.4 dB typ. at 20–30 GHz), isolation (45 dB typ. at 20–30 GHz), and switching time (6 µs 0.1 dB settling)-using 2.4 mm end-launch connectors, coplanar waveguide routing, and optimized thermal grounding.

For engineers reviewing the ADRF5045-EVALZ datasheet, ADRF5045-EVALZ pinout, ADRF5045-EVALZ application, or ADRF5045-EVALZ equivalent, this board enables rapid prototyping of broadband test instrumentation, microwave radios, VSAT front-ends, and military ECM signal routing where ultrawideband RF path control and hot-switching integrity (21 dBm) are critical.

Technical Context

The ADRF5045-EVALZ implements a 4-layer Rogers RO4003-based PCB with top-layer 50 Ω coplanar waveguide traces (14 mil width, 5 mil ground gap), solid inner/ground planes, and plated-through vias for RF and thermal integrity. It interfaces directly with the ADRF5045's 24-terminal LGA package (CC-24-4), supporting dual ±3.3 V supplies and CMOS/LVTTL-compatible V1/V2 control logic.

All five RF ports-RFC, RF1–RF4-are routed to edge-mounted 2.4 mm launchers (J1–J5); a thru-calibration line (J6–J7) enables on-board S-parameter de-embedding. Bypassing includes 100 pF capacitors on VDD/VSS and unpopulated footprints for additional 0.1 µF and 10 µF decoupling per supply rail.

FAQ

What is the primary function of the ADRF5045-EVALZ?

The ADRF5045-EVALZ is a dedicated evaluation board for the ADRF5045 SP4T RF switch. It provides a calibrated, high-fidelity platform to measure insertion loss, isolation, return loss, and switching behavior across 9 kHz–30 GHz. The board uses 2.4 mm launchers, controlled-impedance CPWG routing, and dual-supply support to replicate real-world RF front-end conditions without requiring custom PCB design-enabling immediate characterization of the ADRF5045 in lab and pre-production environments.

Does the ADRF5045-EVALZ support hot switching validation?

Yes, the ADRF5045-EVALZ supports hot switching validation up to 21 dBm, matching the ADRF5045's specified hot-switching rating. Its low-inductance grounding, minimized parasitic coupling, and direct RF port access allow accurate measurement of transient response and power-handling integrity while toggling between RF paths under active RF signal conditions-critical for radar and ECM applications where signal continuity cannot be interrupted.

How is impedance matching maintained across the full 30 GHz bandwidth on the ADRF5045-EVALZ?

Impedance matching is maintained via 50 Ω coplanar waveguide (CPWG) routing-14 mil trace width, 5 mil ground gap-on a 8 mil Rogers RO4003 top layer, backed by solid ground planes on inner and bottom layers. This structure minimizes dispersion and maintains phase stability up to 30 GHz. The board also integrates dense via fencing around RF traces and the ADRF5045's exposed pad to suppress ground bounce and ensure consistent return-path integrity across frequency.

Can the ADRF5045-EVALZ be used with standard VNAs without custom calibration?

Yes-the ADRF5045-EVALZ includes a dedicated thru-calibration line (J6–J7) that enables full 2-port TRL calibration directly on the board. This eliminates the need for external calibration substrates or de-embedding scripts, allowing users to isolate the ADRF5045's intrinsic RF performance from PCB loss, connector mismatch, and launch discontinuities-delivering measurement-grade accuracy from 9 kHz through 30 GHz using standard VNA firmware.

What power supply configuration does the ADRF5045-EVALZ require to operate the ADRF5045?

The ADRF5045-EVALZ requires dual DC supplies: +3.3 V applied to TP1 (VDD) and −3.3 V applied to TP4 (VSS), per the ADRF5045's absolute maximum and recommended operating conditions. Each supply includes a 100 pF bypass capacitor onboard; unpopulated footprints support optional 0.1 µF and 10 µF capacitors for enhanced high-frequency noise suppression-ensuring stable biasing and optimal linearity (P1dB = 28 dBm typ.) during RF testing.
