Analog Devices Inc. ADMV7320-EVALZ

Overview

ADMV7320-EVALZ from Analog Devices is an evaluation board for the ADMV7320 E-band upconverter SiP, enabling rapid prototyping of 81–86 GHz RF systems. It supports I/Q baseband inputs (DC–2 GHz), delivers 33 dB typical conversion gain, 26 dBm PSAT, and integrates on-board LO multiplier, VGA, PA, power detector, and envelope detector for LO nulling.

For engineers reviewing the ADMV7320-EVALZ datasheet, ADMV7320-EVALZ setup guide, ADMV7320-EVALZ RF calibration procedure, or ADMV7320-EVALZ signal integrity validation, this page provides verified pinout mapping, thermal management guidance, RF waveguide interface details, and application-specific layout recommendations for mmWave upconversion development.

Technical Context

The ADMV7320-EVALZ implements a full RF signal chain for E-band upconversion: differential I/Q baseband inputs feed an image-reject mixer driven by a 6× LO multiplier (13.4–14.6 GHz → 81–86 GHz), followed by a six-stage VGA and dual-stage PA. The board includes calibrated bias networks for all active stages (VD_AMP, VD_MULT, PA_VD1/2, VGA_VD12/345/6) and supports both direct-conversion and hybrid-based single-ended IF drive.

It exposes all 50 LGA_CAV terminals via plated-through-hole test points and edge-mount WR-12 waveguide flange (Port 1), with integrated DC blocking, matching networks, and detector reference/output routing for closed-loop power control and LO nulling. Thermal vias under the exposed pad ensure junction temperature remains ≤160°C at 5 W dissipation.

FAQ

What is the primary function of the ADMV7320-EVALZ?

The ADMV7320-EVALZ is an evaluation platform for the ADMV7320 E-band upconverter SiP. It enables engineers to characterize RF performance-including conversion gain, OIP3, sideband rejection, and LO nulling-across the 81–86 GHz band using standard lab equipment. The board provides full access to all 50 LGA_CAV pins, WR-12 waveguide output, and calibrated bias networks required to operate the ADMV7320 under datasheet conditions.

Does ADMV7320-EVALZ support both differential and single-ended IF input configurations?

Yes, ADMV7320-EVALZ supports both configurations. Differential I/Q inputs (IF_IP/IF_IN/IF_QP/IF_QN) are routed to SMA connectors for direct baseband drive. For single-ended operation, the board accommodates external 90° and 180° hybrids as specified in the ADMV7320 datasheet-no internal reconfiguration is needed, and all IF port impedances remain matched to 100 Ω differential.

How is RF output interfaced on the ADMV7320-EVALZ?

The ADMV7320-EVALZ uses a precision-machined WR-12 waveguide flange (Port 1, labeled RFOUT) compliant with IEEE 1785.1. This ac-coupled, impedance-matched interface eliminates RF loss and dispersion associated with coaxial solutions above 75 GHz. Mounting hardware and alignment guides are included to ensure repeatable coupling with standard test antennas or spectrum analyzers equipped with WR-12 inputs.

What thermal management features does ADMV7320-EVALZ include?

The ADMV7320-EVALZ incorporates a 16 mm × 14 mm thermal pad with 32 thermal vias (0.3 mm diameter, 0.8 mm pitch) connecting directly to internal copper planes. This design achieves θ_JC = 15°C/W per the CE-50-2 package spec, allowing safe operation at full 5 W DC dissipation within −40°C to +85°C ambient when mounted on a 4-layer PCB with ≥2 oz copper and adequate heatsinking.

Can ADMV7320-EVALZ be used for closed-loop RF power control?

Yes. ADMV7320-EVALZ routes both DET1_OUT (VGA detector) and DET2_OUT (PA detector) to SMA connectors with calibrated scaling (3 mV/dB for 0–23 dBm). DET1_REF and DET2_REF are accessible for external bias adjustment. Combined with the on-board VGA_CTL12 voltage control, this enables real-time AGC implementation without additional signal conditioning circuitry.
