Analog Devices Inc. EVAL-ADGM1004EBZ

Overview

EVAL-ADGM1004EBZ 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 both parallel (LVTTL) and SPI control interfaces, SMA RF connectors, and on-board calibration transmission line for vector network analyzer de-embedding - used in RF front-end prototyping, mmWave test fixtures, and high-frequency switch validation.

For engineers reviewing the EVAL-ADGM1004EBZ datasheet, EVAL-ADGM1004EBZ pinout, EVAL-ADGM1004EBZ application, or EVAL-ADGM1004EBZ equivalent, this page delivers verified hardware interface details, SPI/parallel configuration modes, PCB stackup specifications, calibration methodology, and integration requirements with SDP-B controller and ACE software.

Technical Context

The EVAL-ADGM1004EBZ implements a full-function hardware interface to the ADGM1004 MEMS switch, which integrates a 3.3 V–powered control IC generating internal 80 V boost for actuation. It supports dual control paths: 4-bit parallel LVTTL logic (IN1–IN4) and 4-wire SPI (SDI, SDO, SCLK, CSB), with configurable MODE and EXTD_EN jumpers.

Its RF path uses six 50 Ω SMA edge launch connectors (RF1–RF4, RFC, plus RF5/RF6 calibration thru-line), all routed on Rogers RO4003C laminate with coplanar waveguide geometry (15 mil trace, 12.2 mil gap), enabling accurate 13 GHz measurement after de-embedding using the matched-length calibration line.

FAQ

What is the primary function of the EVAL-ADGM1004EBZ?

The EVAL-ADGM1004EBZ is an evaluation board for the ADGM1004 SP4T MEMS switch, providing full hardware access to its RF ports (RFC, RF1–RF4), control interfaces (parallel and SPI), and on-board calibration infrastructure. It enables precise S-parameter measurement, switching state verification, and system-level integration testing of the ADGM1004 under real-world RF conditions up to 13 GHz.

Does the EVAL-ADGM1004EBZ require external power, and what voltage is needed?

Yes, the EVAL-ADGM1004EBZ requires an external 3.3 V DC power supply connected to the P5 terminal block. The board draws power for both the ADGM1004's control IC and onboard logic. No other supply voltages are required when using the internal 10 MHz oscillator (EXTD_EN set to INT); if EXT mode is selected, an external 80 V DC must be applied to the EXT_VCP SMB connector.

How is network analyzer calibration performed using the EVAL-ADGM1004EBZ?

Calibration uses the dedicated RF5–RF6 calibration thru-line, which matches the electrical length of each RFx-to-device trace. Users measure S(2,1) of the thru-line, then divide the full switch measurement (e.g., RF1–RFC) by that reference to de-embed PCB loss. Phase offset is corrected via network analyzer port extension using half the thru-line time delay - values derived directly from the EVAL-ADGM1004EBZ's documented CPWG geometry and laminate stackup.

Which software and hardware are required to operate the EVAL-ADGM1004EBZ via SPI?

Operation via SPI requires the EVAL-SDP-CB1Z (SDP-B) controller board, a USB cable, a Windows PC, and Analog Devices' ACE (Analysis, Control, Evaluation) software. The ACE software provides register-level control, memory map editing, and graphical switch toggling. Links P1–P4 must be set to SDI, CSB, SCLK, and SDO respectively, and the MODE jumper must be set to SPI position before connecting to the SDP-B board.

Can the EVAL-ADGM1004EBZ be used without the SDP-B controller board?

Yes - the EVAL-ADGM1004EBZ supports standalone operation via its parallel LVTTL interface. By setting the MODE jumper to PIN and configuring IN1–IN4 links (or applying external logic signals to the IN1–IN4 SMB connectors), users can manually select RF paths without any host controller. This mode requires no software, USB connection, or SDP-B board, making it suitable for bench-level functional validation and quick-switching tests.
