Analog Devices Inc. ADMV8913-EVALZ

Overview

ADMV8913-EVALZ from Analog Devices is an evaluation board for the ADMV8913-EP digitally tunable X-band high-pass and low-pass filter IC. It enables rapid characterization of 6.6–11.9 GHz passband tuning, 4-bit per filter digital control, 5.3 dB typical insertion loss, 35 dB wideband rejection, and operation across −55°C to +105°C for defense radar and electronic warfare systems.

For engineers reviewing the ADMV8913-EVALZ datasheet, ADMV8913-EVALZ pinout, ADMV8913-EVALZ application, or ADMV8913-EVALZ equivalent, this board provides full SPI and parallel interface access to the ADMV8913-EP's tunable HPF/LPF architecture, on-board LDO support, RF calibration traces, and military-grade thermal/mechanical validation per AQEC standards.

Technical Context

The ADMV8913-EVALZ implements a fully populated reference design for the ADMV8913-EP MMIC, featuring matched 50 Ω RF input (RF1) and output (RF2) paths with dc coupling, precision decoupling networks for VDD1 (2.5 V), VDD2 (3.3 V), and VSS1 (−2.5 V), and dual-mode digital control via SPI (SCLK/CS/SDI/SDO/SFL) or parallel logic (HPF_B0–B3, LPF_B0–B3).

It supports all three operational modes-SPI write, SPI fast latch (128-state LUT), and parallel programming-and includes hardware reset (RST), mode select (PS), and LDO enable (LDO_EN) interfaces. The PCB uses Rogers 4350B dielectric with controlled-impedance microstrip routing and direct-exposed-pad grounding per Analog Devices' RF layout guidelines.

FAQ

What is the primary function of the ADMV8913-EVALZ?

The ADMV8913-EVALZ is an evaluation board designed exclusively for the ADMV8913-EP tunable X-band filter IC. It provides complete hardware access to all RF and digital pins-including RF1, RF2, SPI, parallel control, power supplies, and reset-enabling engineers to validate 6.6–11.9 GHz bandpass tuning, measure insertion loss/rejection, and verify timing performance per the ADMV8913-EP datasheet Rev. A specifications.

Does ADMV8913-EVALZ support both SPI and parallel programming modes?

Yes, ADMV8913-EVALZ fully supports both SPI and parallel programming of the ADMV8913-EP. It exposes SCLK, CS, SDI, SDO, and SFL for SPI configuration, and HPF_B0–B3 / LPF_B0–B3 for direct parallel logic control. The PS pin is accessible to toggle between modes, and all control lines include 260 kΩ internal pull resistors as implemented on the ADMV8913-EP die.

What RF connector type is used on ADMV8913-EVALZ?

The ADMV8913-EVALZ uses SMA female connectors for both RF1 and RF2 ports. These are dc-coupled, 50 Ω impedance-matched interfaces aligned to the ADMV8913-EP's internal RF architecture. No external dc blocking capacitors are needed unless system-level dc bias is present-per the ADMV8913-EP datasheet recommendation.

Can ADMV8913-EVALZ operate across the full military temperature range?

Yes, ADMV8913-EVALZ is qualified for operation from −55°C to +105°C, matching the ADMV8913-EP's extended temperature rating. Its Rogers 4350B PCB substrate, selected passive components, and layout adherence to Analog Devices' AQEC-compliant guidelines ensure stable RF performance and digital interface integrity across the full military temperature range.

Is the LDO regulator on ADMV8913-EVALZ enabled by default?

Yes, the ADMV8913-EVALZ configures the ADMV8913-EP's on-chip LDO regulator by default: the LDO_EN pin is left floating (internally pulled high), enabling the 2.5 V VDD1 supply generation. External VDD1 voltage must not be applied when the LDO is active. VDD2 (3.3 V) and VSS1 (−2.5 V) are supplied externally through dedicated screw terminals with proper decoupling.
