Analog Devices Inc. EVAL-ADGM1004SDZ

Overview

EVAL-ADGM1004SDZ from Analog Devices is an evaluation board designed to characterize the ADGM1004 0 Hz/DC to 13 GHz SP4T MEMS switch with integrated driver, supporting RF performance validation up to 16 GHz via SMA connectors and on-board calibration transmission line. It enables SPI and parallel LVTTL control of switch states (RF1–RF4 to RFC), powered by a single 3.3 V supply.

For engineers reviewing the EVAL-ADGM1004SDZ datasheet, EVAL-ADGM1004SDZ pinout, EVAL-ADGM1004SDZ application, or EVAL-ADGM1004SDZ equivalent, this board provides full hardware/software integration with ACE software, SDP-B controller, vector network analyzer calibration, and configurable link-based switching for lab-grade RF switch characterization.

Technical Context

The EVAL-ADGM1004SDZ interfaces directly with the ADGM1004 MEMS switch and its co-packaged control IC, enabling both parallel (IN1–IN4) and SPI (SDI/CSB/SCLK/SDO) operation modes via jumper-selectable links. It supports internal 10 MHz oscillator (INT mode) or external 80 V DC drive (EXT mode) for MEMS actuation.

Its PCB uses Rogers RO4003C dielectric (ε_r = 3.38) with coplanar waveguide (CPWG) RF traces (15 mil width, 12.2 mil gap), precisely matched to the calibration thru-line length (A + B) for de-embedding up to 16 GHz - ensuring accurate S-parameter extraction of insertion loss, return loss, and off-isolation.

FAQ

What is the maximum RF frequency supported by the EVAL-ADGM1004SDZ evaluation board?

The EVAL-ADGM1004SDZ evaluation board supports RF measurements up to 16 GHz, as confirmed by its calibrated CPWG transmission line and network analyzer validation procedure. This upper limit applies to both insertion loss and off-isolation characterization when using the on-board RF5–RF6 calibration thru-line for de-embedding. The underlying ADGM1004 device operates from 0 Hz/DC to 13 GHz.

Does the EVAL-ADGM1004SDZ require an external controller board to operate?

Yes, the EVAL-ADGM1004SDZ requires the EVAL-SDP-CB1Z (SDP-B) system demonstration platform controller board to enable SPI communication with a PC via USB. The SDP-B board provides the physical interface, power distribution, and digital protocol translation needed for ACE software control of the ADGM1004 switch states.

How does the on-board calibration transmission line (RF5–RF6) improve measurement accuracy on the EVAL-ADGM1004SDZ?

The RF5–RF6 calibration thru-line on the EVAL-ADGM1004SDZ has identical electrical length to the sum of any RFx-to-ADGM1004 and RFC-to-ADGM1004 trace paths (A + B). This allows precise de-embedding of PCB trace loss and phase offset from raw S-parameter measurements - enabling true device-level insertion loss and return loss data up to 16 GHz without fixture error.

Can the EVAL-ADGM1004SDZ be used with only parallel logic control, without SPI or ACE software?

Yes, the EVAL-ADGM1004SDZ supports standalone parallel control using the IN1–IN4 SMB connectors or on-board links (P1–P4 set to D_IN1–D_IN4). No SDP-B board, USB connection, or ACE software is required when operating in PIN mode - allowing manual or microcontroller-driven switching of RF1–RF4 paths to RFC using 3.3 V LVTTL logic levels.

What power supply requirements must be met to operate the EVAL-ADGM1004SDZ?

The EVAL-ADGM1004SDZ requires a clean, regulated 3.3 V DC power supply connected to the P5 terminal block, with polarity referenced to the PCB's silkscreen-marked GND. Current draw depends on mode: ~50 μA in EXT mode (external 80 V applied), higher in INT mode due to internal oscillator and boost circuitry. No onboard voltage regulation is provided.
