Analog Devices Inc. ADMV8416-EVALZ

Overview

ADMV8416-EVALZ from Analog Devices is an evaluation board for the ADMV8416 monolithic microwave integrated circuit (MMIC) tunable band-pass filter, supporting 6.3 GHz to 18 GHz passband operation with analog center-frequency tuning (0–15 V), dual-band selection (VCTL = 0 V or 2.5 V), and 40-lead LFCSP package. It enables rapid characterization of insertion loss, rejection, group delay flatness, and phase sensitivity in RF front-end designs.

For engineers reviewing the ADMV8416-EVALZ datasheet, ADMV8416-EVALZ pinout, ADMV8416-EVALZ application, or ADMV8416-EVALZ equivalent, this board provides full access to all control interfaces (VTUNE, VCTL, VDD, VEE), RF input/output paths with 50 Ω SMA connectors, on-board decoupling, and ground-plane optimized layout for mmWave measurement integrity up to 40 GHz.

Technical Context

The ADMV8416-EVALZ implements a calibrated test platform for the ADMV8416 MMIC filter, featuring discrete bias networks for VDD (+5 V), VEE (−5 V), VTUNE (0–15 V), and VCTL (0 V / 2.5 V), each with precision voltage regulation and filtering. The board supports both high-band (12.6–16.8 GHz) and low-band (6.8–12 GHz) operation via jumper-selectable VCTL configuration.

It integrates matched 50 Ω microstrip traces from SMA edge-mount connectors to the ADMV8416 RFIN and RFOUT pins, maintains controlled impedance across the full 6.3–18 GHz operating range, and includes thermal vias and EPAD grounding per the LFCSP package requirements. No onboard signal generation or detection circuitry is included - it is strictly a passive interface and biasing platform.

FAQ

What is the primary function of the ADMV8416-EVALZ?

The ADMV8416-EVALZ is a dedicated evaluation board for the ADMV8416 tunable band-pass filter IC. It provides complete biasing (VDD, VEE, VTUNE, VCTL), RF signal routing via SMA connectors, and proper grounding per the 40-lead LFCSP package requirements - enabling direct measurement of insertion loss, rejection, group delay, and tuning linearity without custom PCB development. The ADMV8416-EVALZ does not include active signal sources or detectors.

Does the ADMV8416-EVALZ support both high-band and low-band operation of the ADMV8416?

Yes, the ADMV8416-EVALZ supports both bands via a configurable VCTL interface: applying 0 V selects the high-band mode (fCENTER = 12.6–16.8 GHz), while 2.5 V selects the low-band mode (fCENTER = 6.8–12 GHz). Jumper options or external voltage sources allow seamless switching between bands during characterization - matching the exact VCTL specifications defined in the ADMV8416 datasheet Table 3 and Theory of Operation section.

What RF connector type and impedance does the ADMV8416-EVALZ use?

The ADMV8416-EVALZ uses edge-mount SMA connectors on both input and output, with 50 Ω impedance-matched microstrip traces routed directly to the RFIN and RFOUT pins of the ADMV8416 IC. These traces are optimized for minimal discontinuity across 6.3–18 GHz, and the board requires external dc-blocking capacitors on RFIN/RFOUT if the connected RF source or load presents non-zero DC potential - as specified in the ADMV8416 Applications Information section.

Can the ADMV8416-EVALZ be used for phase-sensitive measurements?

Yes - the ADMV8416-EVALZ preserves the phase integrity of the ADMV8416, supporting phase sensitivity measurements (0.7–1.21 rad/V) and group delay flatness (≤0.2 ns typical) as documented in the datasheet. Its symmetric, ground-via-rich layout, EPAD grounding, and absence of active components ensure minimal added phase distortion, making it suitable for vector network analyzer (VNA) calibration and phase-shift vs. VTUNE characterization per Figures 44–45.

Is thermal management provided on the ADMV8416-EVALZ for extended mmWave operation?

Yes - the ADMV8416-EVALZ implements robust thermal design per the ADMV8416's LFCSP package requirements: the exposed paddle (EPAD) is soldered to a large internal copper plane with multiple thermal vias connecting to top and bottom ground layers. This structure ensures effective heat dissipation during continuous-wave RF testing up to +85°C ambient, aligning with the ADMV8416's specified junction temperature limits and MTTF reliability targets.
