Analog Devices Inc. EVAL-ADF5000EB2Z

Overview

EVAL-ADF5000EB2Z from Analog Devices is an evaluation board for the ADF5000 4 GHz–18 GHz divide-by-2 RF prescaler IC, designed to validate high-frequency PLL frequency extension in microwave systems. It supports differential 6 GHz output from 12 GHz input, operates from a single 3.3 V supply, features SMA RF connectors (J2/J3/J4), and enables CE-controlled power-down mode.

For engineers reviewing the EVAL-ADF5000EB2Z datasheet, EVAL-ADF5000EB2Z pinout, EVAL-ADF5000EB2Z application, or EVAL-ADF5000EB2Z equivalent, this board provides verified RF layout, Rogers RO4003C PCB stack-up, calibrated 50 Ω impedance traces, and direct interface to ADF4156/ADF4106 PLLs - critical for microwave radio, VSAT, and test equipment design validation.

Technical Context

The EVAL-ADF5000EB2Z implements the ADF5000BCPZ prescaler in a controlled RF environment with precision 50 Ω microstrip routing on Rogers RO4003C (ε_r = 3.38). It supports both single-ended and differential RF interfacing, with J4 as the 4–18 GHz input port and J2/J3 as complementary 2–9 GHz differential outputs.

Power delivery uses T3 (VDDx) and T2 (GND) test points or J1 SMA connector (3.0–3.6 V), while CE control is accessible at T1. Unused RF outputs require 50 Ω termination to maintain signal integrity and minimize reflections above 10 GHz.

FAQ

What is the primary function of the EVAL-ADF5000EB2Z evaluation board?

The EVAL-ADF5000EB2Z evaluation board is designed exclusively to evaluate the ADF5000BCPZ divide-by-2 RF prescaler IC. It provides a fully laid-out, impedance-controlled platform with SMA connectors, proper decoupling, and thermal grounding to validate 4–18 GHz RF division performance, differential output integrity, and CE-controlled power-down behavior in real-world PLL designs. The board directly supports integration with ADF4156 and ADF4106 PLLs.

Which RF connectors are used on the EVAL-ADF5000EB2Z and what are their roles?

The EVAL-ADF5000EB2Z uses four Emerson SMA connectors: J4 (input) accepts 4–18 GHz RF signals; J2 and J3 (outputs) deliver complementary 2–9 GHz differential RF signals; J1 supplies 3.0–3.6 V power. All connectors are mechanically compatible with SMA, 3.5 mm, and 2.92 mm cables. Unused RF outputs must be terminated with 50 Ω loads to preserve signal fidelity above 10 GHz.

Does the EVAL-ADF5000EB2Z support single-ended or differential operation of the ADF5000BCPZ?

Yes - the EVAL-ADF5000EB2Z supports both configurations. It routes the ADF5000BCPZ's RFOUT and RFOUT pins to separate SMA connectors (J2 and J3) for differential use, and allows single-ended operation by terminating one output. The board's layout preserves 50 Ω impedance in either mode, and its Rogers RO4003C substrate ensures minimal loss and phase skew up to 18 GHz.

How is power delivered and managed on the EVAL-ADF5000EB2Z?

Power is delivered via J1 (SMA connector) or test points T3 (VDDx) and T2 (GND), supporting 3.0–3.6 V. The board replicates the ADF5000BCPZ's dual-supply architecture: VDD1 powers the input stage and divider, VDD2 powers the output stage. Decoupling uses 0.1 µF + 10 pF capacitors per supply pin, matching the datasheet-recommended network for stable 30 mA active and 17 mA power-down current draw.

What PCB material and stack-up does the EVAL-ADF5000EB2Z use, and why is it critical?

The EVAL-ADF5000EB2Z uses Rogers RO4003C (0.008″ thick, ε_r = 3.38) with a 4-layer stack-up optimized for 50 Ω microstrip routing. This material minimizes dielectric loss and dispersion above 10 GHz - essential for preserving phase noise (−147 dBc/Hz @ 100 kHz offset) and harmonic suppression (−28 dBc 2nd, −12 dBc 3rd) measured on the ADF5000BCPZ. FR4 prepreg layers provide structural stability without compromising RF performance.
