Analog Devices Inc. EV1HMC547ALC3

Overview

EV1HMC547ALC3 from Analog Devices is an evaluation PCB designed to characterize the HMC547ALC3 GaAs MMIC SPDT non-reflective switch, supporting DC–28 GHz operation with 45 dB isolation at 10 GHz, 1.9 dB insertion loss at 10 GHz, and 6 ns switching time in military EW/ECM and microwave test instrumentation.

For engineers reviewing the EV1HMC547ALC3 datasheet, EV1HMC547ALC3 pinout, EV1HMC547ALC3 application, or EV1HMC547ALC3 equivalent, this board provides verified RF layout, SMA connectors (J1–J3), DC control pins (J4–J6), 100 Ω termination resistors (R1–R2), and Rogers 4350 substrate for accurate high-frequency switch validation under real-world impedance-matched conditions.

Technical Context

The EV1HMC547ALC3 is a dedicated evaluation platform-not an IC-built around the HMC547ALC3 switch in a 16-lead 3×3 mm ceramic SMT package. It implements full 50 Ω RF routing, grounded paddle soldering, and dual negative-control logic (A/B) interface compatible with –5 V/0 V logic levels.

Its design enforces RF best practices: controlled-impedance signal lines, direct grounding of all package leads and exposed paddle, SMA connector placement aligned with RFC/RF1/RF2 ports, and on-board 100 Ω terminations for stable off-state isolation measurement per Analog Devices' recommended test setup.

FAQ

What is the EV1HMC547ALC3 used for?

The EV1HMC547ALC3 is an evaluation PCB specifically built to test and validate the HMC547ALC3 GaAs SPDT switch under real RF conditions. It enables accurate measurement of insertion loss, isolation, switching speed, and linearity from DC to 28 GHz using SMA interfaces and proper grounding-critical for defense and test equipment design. The EV1HMC547ALC3 does not function as a standalone IC but as a turnkey characterization platform.

Does the EV1HMC547ALC3 include the HMC547ALC3 IC?

Yes, the EV1HMC547ALC3 evaluation board includes one mounted HMC547ALC3 IC (U1) in its 16-lead 3×3 mm ceramic package. The board is shipped fully assembled with SMA connectors (J1–J3), DC control pins (J4–J6), and 100 Ω termination resistors (R1–R2), ready for immediate RF testing without additional component assembly. The EV1HMC547ALC3 is not a bare PCB-it is a functional evaluation system.

What are the key RF layout features of the EV1HMC547ALC3?

The EV1HMC547ALC3 implements strict RF layout rules: 50 Ω microstrip routing to all RF ports, direct connection of all GND pins and the exposed paddle to a solid ground plane, minimal via stubs, and SMA launch geometry optimized for <1.5 dB insertion loss up to 28 GHz. Its Rogers 4350 substrate ensures low dispersion and stable phase response-essential for validating the HMC547ALC3's performance across its full bandwidth. This makes the EV1HMC547ALC3 ideal for repeatable lab measurements.

Can the EV1HMC547ALC3 be used for automated test equipment (ATE) integration?

Yes, the EV1HMC547ALC3 supports ATE integration via its standardized SMA RF ports (J1–J3) and accessible DC control pins (J4–J5). Its deterministic layout, known parasitic profile, and compatibility with –5 V/0 V logic enable precise timing correlation between control signals and RF switching edges-critical for bit-error-rate testing and swept-frequency characterization. The EV1HMC547ALC3 delivers the repeatability needed for production-grade RF switch validation in ATE environments.

Is thermal management addressed on the EV1HMC547ALC3 board?

Yes, thermal management is integral to the EV1HMC547ALC3 design: the HMC547ALC3's exposed paddle is soldered directly to a large copper ground plane, and all 16 package leads-including dedicated GND pins-are connected to that same plane. This configuration replicates the thermal resistance (118 °C/W for insertion path, 200 °C/W for terminated path) specified in the HMC547ALC3 datasheet, enabling realistic power-handling validation up to +23 dBm hot-switch and +25 dBm terminated conditions. The EV1HMC547ALC3 thus supports thermally accurate switch evaluation.
