Analog Devices Inc. ADMV1014-EVALZ

Overview

ADMV1014-EVALZ from Analog Devices is a fully featured evaluation board for the ADMV1014 24.5 GHz to 43.5 GHz wideband microwave downconverter. It integrates the ADMV1014 SiGe IC, a PIC18F24J50 microcontroller, AD5601 nanoDAC®, LDO regulators (1.5 V, 1.8 V, 3.3 V), and USB-SPI interface - enabling rapid characterization of direct-conversion I/Q and image-rejecting IF modes in point-to-point radio applications.

For engineers reviewing the ADMV1014-EVALZ datasheet, ADMV1014-EVALZ pinout, ADMV1014-EVALZ application, or ADMV1014-EVALZ equivalent, this board supports SPI-controlled register configuration via ACE software, on-board VCTRL voltage tuning (0–3300 mV), dual-mode RF/LO signal routing (2.92 mm connectors), and lab-ready IF/IQ output interfaces with hybrid coupling guidance.

Technical Context

The ADMV1014-EVALZ implements a complete test platform for the ADMV1014 downconverter, featuring differential LO input (LO_P/LO_N) supporting 5.4–10.25 GHz with internal ×4 quadrupler, RF input via 2.92 mm connector (24.5–43.5 GHz), and dual-output capability: four-pin I/Q baseband (I_P/I_N/Q_P/Q_N) or two-pin complex IF (IF_I/IF_Q) up to 6 GHz. The board uses a PIC18F24J50 microcontroller to manage SPI communication and register mapping.

It provides on-board power regulation (ADP7102ARDZ-1.5, ADM7170ACPZ-1.8), AD5601 nanoDAC® for precise VCTRL control (0–3300 mV), and hardware-level reset (S1 button). Signal routing includes dedicated test points for VDET, VCTRL, and supply rails, with ac-coupled I/Q outputs and dc-coupled IF paths compliant with spectrum and baseband analyzer interfacing requirements.

FAQ

What is the primary function of the ADMV1014-EVALZ?

The ADMV1014-EVALZ is an evaluation board purpose-built to characterize the ADMV1014 24.5–43.5 GHz wideband downconverter. It enables engineers to validate both direct quadrature demodulation (I/Q baseband) and image-rejecting complex IF operation, with full SPI register control via ACE software, on-board power regulation, and calibrated RF/LO/IF signal routing - all without external DACs, controllers, or discrete power supplies.

Does the ADMV1014-EVALZ require external power supplies beyond 5 V?

No. The ADMV1014-EVALZ operates from a single 5 V dc input and internally generates all required supply rails: 1.5 V for LNA bias, 1.8 V for digital core/SPI, and 3.3 V for mixer/VGA stages using integrated ADP7102ARDZ-1.5 and ADM7170ACPZ-1.8 LDO regulators. No external power supplies are needed for standard evaluation.

How is SPI communication implemented on the ADMV1014-EVALZ?

SPI communication on the ADMV1014-EVALZ is handled by an onboard PIC18F24J50 microcontroller, which bridges USB commands from the ACE software to the ADMV1014's serial port interface. The board uses FXL4TD245BQX level shifters to ensure correct voltage translation between the microcontroller (3.3 V logic) and ADMV1014 (1.8 V SPI interface), with SCLK, SDI, and SDO routed directly to the IC.

Can the ADMV1014-EVALZ be used for both I/Q and IF mode evaluation simultaneously?

No. The ADMV1014-EVALZ supports either I/Q baseband mode (using I_P/I_N/Q_P/Q_N) or complex IF mode (using IF_I/IF_Q), but not both simultaneously. When IF mode is enabled, the I/Q outputs are left floating per design; when I/Q mode is active, IF outputs are disabled. The ACE software enforces this through register controls (BB_AMP_PD and IF_AMP_PD bits) and indicates invalid dual-path activation with a red LED.

What software and drivers are required to operate the ADMV1014-EVALZ?

To operate the ADMV1014-EVALZ, users must install Analog Devices' ACE software, the ADMV1014 plugin (Board.ADMV1014.ace.zip), and USB drivers for the ADMV1014-045188 RevA device. The ACE interface provides graphical register control, memory map access, VCTRL tuning via AD5601 nanoDAC®, and real-time readback of status bits including parity, address range, and error mask flags.
