Analog Devices Inc. EVAL-ADGM1001SDZ

Overview

EVAL-ADGM1001SDZ from Analog Devices is an evaluation board designed to characterize the ADGM1001 - a 0 Hz/DC to 34 GHz, single-pole double-throw (SPDT) MEMS switch with integrated control IC in a 5.00 mm × 4.00 mm × 0.90 mm LGA package. It supports parallel (LVTTL/CMOS) and SPI interfaces, features SMA/2.92 mm RF connectors, on-board CALIBRATION THRU transmission line, and operates from a 3.3 V supply.

For engineers reviewing the EVAL-ADGM1001SDZ datasheet, EVAL-ADGM1001SDZ pinout, EVAL-ADGM1001SDZ application, or EVAL-ADGM1001SDZ equivalent, this board enables full RF performance validation of the ADGM1001 MEMS switch - including insertion loss, return loss, off-isolation, and phase-corrected S-parameter measurements up to 34 GHz using vector network analyzer calibration workflows.

Technical Context

The EVAL-ADGM1001SDZ implements a dual-chip evaluation platform: one ADGM1001BCCZ MEMS switch and its companion control IC, both co-packaged. The board provides direct access to RF1, RF2, and RFC ports via 2.92 mm end-launch connectors rated to 40 GHz, plus RFC1/RFC2 calibration lines matched in electrical length to the signal paths.

Control is implemented via configurable jumpers (P1–P6, K1–K4) supporting either parallel interface (IN1/IN2 logic) or SPI (SDI/CSB/SCLK/SDO), with internal 10 MHz oscillator (INT) or external 80 V VCP drive (EXT) selection. Power is supplied via Mini-USB (J5) or external 3.3 V terminal block (P7), with JP7 selecting source.

FAQ

What is the primary function of the EVAL-ADGM1001SDZ evaluation board?

The EVAL-ADGM1001SDZ evaluation board is designed exclusively to evaluate the ADGM1001BCCZ - a 0 Hz/DC to 34 GHz SPDT MEMS switch with integrated control IC. It provides calibrated RF signal paths, dual digital interfaces (parallel and SPI), and hardware-level configuration options to measure insertion loss, return loss, isolation, and switching timing under real-world conditions. The EVAL-ADGM1001SDZ does not operate as a standalone functional module but serves strictly as a characterization platform for the ADGM1001 device.

Which RF connectors are used on the EVAL-ADGM1001SDZ and what is their frequency rating?

The EVAL-ADGM1001SDZ uses Southwest Microwave 1092-04A-12 2.92 mm female end-launch connectors for RF1, RF2, RFC, RFC1, and RFC2. These connectors are rated to 40 GHz and are optimized for low reflection and repeatable connection in high-frequency test environments. Their mechanical design minimizes launch discontinuity, enabling accurate S-parameter measurements of the ADGM1001 up to its full 34 GHz operational bandwidth.

Does the EVAL-ADGM1001SDZ require an external controller board to operate, and if so, which one?

Yes, the EVAL-ADGM1001SDZ requires the EVAL-SDP-CB1Z (SDP-B) controller board for SPI-based operation. The SDP-B connects via USB to a PC and interfaces with the EVAL-ADGM1001SDZ through a 120-pin connector (P8). It supplies power and routes SPI signals (SDI, CSB, SCLK, SDO) to the board. For parallel interface use, only a 3.3 V supply and logic-level control signals are needed - no SDP-B required. ACE software with the EVAL-ADGM1001SDZ plug-in is mandatory for SPI control and register-level configuration.

How does the CALIBRATION THRU transmission line on the EVAL-ADGM1001SDZ improve measurement accuracy?

The CALIBRATION THRU line on the EVAL-ADGM1001SDZ is a precisely matched 50 Ω coplanar waveguide path identical in electrical length to the sum of the RF1→ADGM1001 and RFC→ADGM1001 trace paths. By measuring its S(2,1) response, users can mathematically de-embed PCB trace loss and phase delay from raw switch measurements - correcting for insertion loss and applying port extension to eliminate phase offset. This enables true device-level S-parameter extraction up to 35 GHz without fixture error.

Can the EVAL-ADGM1001SDZ be powered solely via USB, and what are the jumper settings required?

Yes, the EVAL-ADGM1001SDZ can be powered solely via the Mini-USB connector (J5) by setting JP7 to position A. In this configuration, no external 3.3 V supply is needed. The board draws regulated 3.3 V from the USB host, sufficient to power the ADGM1001 control IC and enable MEMS actuation. All other jumpers (P1–P6, K1–K4) remain configurable per interface mode - for example, P5 set to SPI and P6 to INT for default SPI operation with internal 10 MHz clock.
