Analog Devices Inc. ADMV8513-EVALZ

Overview

ADMV8513-EVALZ from Analog Devices is an evaluation board for the ADMV8513 digitally tunable RF band-pass filter IC, supporting center frequency tuning from 520 MHz to 1300 MHz via 8-bit SPI control. It enables rapid characterization of insertion loss (typ. 5.5 dB), 3 dB bandwidth (8.5% ±2%), and 20 dB rejection (±17% from f_CENTER) in lab and design validation environments.

For engineers reviewing the ADMV8513-EVALZ datasheet, ADMV8513-EVALZ setup, ADMV8513-EVALZ test procedure, or ADMV8513-EVALZ compatibility with ADMV8513 filter ICs, this board provides a fully populated, impedance-matched platform with calibrated RF ports, on-board decoupling, and SPI interface headers - optimized for land mobile radio, EW/ECM, satellite comms, and test equipment prototyping.

Technical Context

The ADMV8513-EVALZ implements the full functional interface of the ADMV8513 IC, including its 40-terminal LGA package footprint, dual 50 Ω RF ports (RF1/RF2), and 5-line SPI bus (CS, SCLK, SDI, SDO, SFL) with configurable fast-latch mode. It supports both SPI write and streaming protocols per ADI-SPI standard, with register access to interpolation coefficients, LUT configuration, and real-time capacitor code readback.

Board-level design incorporates matched 50 Ω microstrip routing, dedicated VDD (+3.3 V) and VSS (−2.5 V) power planes with multi-stage decoupling (47 µF/0.1 µF/100 pF), and thermal management via direct EPAD grounding. It operates across −40°C to +85°C ambient, matching the ADMV8513's specified temperature range and ESD rating (HBM 1000 V, FICDM 500 V).

FAQ

What is the primary function of the ADMV8513-EVALZ?

The ADMV8513-EVALZ is a fully assembled evaluation board for the ADMV8513 digitally tunable band-pass filter IC. It provides immediate RF characterization capability - including S-parameter measurement, SPI register access, and dynamic bandwidth/frequency tuning verification - without custom PCB design. The board directly interfaces with standard lab equipment and microcontroller-based controllers via its exposed SPI header and SMA RF ports.

Does ADMV8513-EVALZ support both SPI write and fast-latch modes?

Yes, ADMV8513-EVALZ fully supports both operational modes of the ADMV8513 IC. Its SFL pin is accessible via header, enabling seamless transition between SPI write mode (SFL = low) and SPI fast-latch mode (SFL = high), where filter states cycle on each CS rising edge using the internal 32-entry LUT. All required timing constraints (e.g., t₁₁, t₁₂, t₁₃) are met by the board's layout and component selection.

Can ADMV8513-EVALZ be used to calibrate interpolation coefficients for the ADMV8513?

Yes, ADMV8513-EVALZ enables full interpolation coefficient calibration as described in the ADMV8513 datasheet. It allows real-time readback of applied capacitor codes (via Registers 0x060–0x062), adjustment of f_CENTER, bandwidth, and match load values, and verification of resulting RF performance - all critical for optimizing narrow/wide bandwidth operation and compensating for process variation across device lots.

What RF performance metrics can be measured directly using ADMV8513-EVALZ?

Using ADMV8513-EVALZ with a vector network analyzer, engineers can directly measure insertion loss (typ. 5.5 dB), return loss (≥20 dB), 3 dB bandwidth (8.5% ±2%), 20 dB rejection offset (±17% from f_CENTER), group delay (9 ns at 520 MHz), and amplitude/phase settling times (4 µs / 9 µs). These measurements reflect the true ADMV8513 IC behavior under controlled, production-representative conditions.

Is external power regulation required for ADMV8513-EVALZ operation?

No - ADMV8513-EVALZ accepts +3.3 V and −2.5 V via screw terminals or headers and includes onboard bulk, ceramic, and high-frequency decoupling (47 µF, 0.1 µF, 100 pF per supply rail), satisfying ADMV8513's static and dynamic current requirements (IDD ≤ 2.5 mA at 10 MHz SCLK). External LDOs are optional but recommended for ultra-low-noise applications.
