Analog Devices Inc. EV1HMC349AMS8G

Overview

EV1HMC349AMS8G from Analog Devices is an evaluation board for the HMC349AMS8G GaAs SPDT RF switch, supporting 100 MHz to 4 GHz operation with 57 dB isolation at 2 GHz, 0.9 dB insertion loss at 2 GHz, and CMOS/TTL-compatible control logic. It enables rapid validation of high-isolation RF path switching in cellular infrastructure and test equipment.

For engineers reviewing the EV1HMC349AMS8G datasheet, EV1HMC349AMS8G pinout, EV1HMC349AMS8G application, or EV1HMC349AMS8G equivalent, this board provides a fully populated, 4-layer reference design with SMA connectors, 100 pF dc-blocking capacitors, coplanar waveguide routing, and thermal vias under the exposed pad - optimized for RF performance verification and thermal characterization of the HMC349AMS8G switch.

Technical Context

The EV1HMC349AMS8G implements a 4-layer PCB stackup: top layer uses 10 mil Rogers RO4350 for RF integrity, while inner and bottom layers are grounded FR-4 planes. All RF traces use coplanar waveguide geometry (16 mil width, 13 mil ground spacing) to maintain 50 Ω impedance.

It integrates three PC-mount SMA connectors (J1/RFC, J2/RF2, J3/RF1), dedicated test points for VDD (TP2), CTRL (TP3), EN (TP4), and GND (TP1, TP5), plus unpopulated positions for bypass capacitors (C4–C6) and thru-line calibration (J4–J5). The HMC349AMS8G IC is mounted with its exposed pad soldered directly to the ground plane.

FAQ

What is the primary function of the EV1HMC349AMS8G?

The EV1HMC349AMS8G is an evaluation board - not an IC - built to validate the performance of the HMC349AMS8G GaAs SPDT RF switch. It provides a ready-to-use, calibrated platform with SMA connectors, proper RF layout, and thermal vias to measure insertion loss, isolation, and linearity across 100 MHz to 4 GHz before integrating the HMC349AMS8G into custom designs.

Does the EV1HMC349AMS8G include the HMC349AMS8G IC?

Yes, the EV1HMC349AMS8G evaluation board is shipped with the HMC349AMS8G IC pre-mounted and soldered. The board is fully populated per the schematic in the datasheet, including C1–C3 (100 pF dc-blocking capacitors), test points, and SMA connectors - enabling immediate RF testing without assembly.

What RF frequency range does the EV1HMC349AMS8G support?

The EV1HMC349AMS8G supports the full operational bandwidth of the HMC349AMS8G: 100 MHz to 4 GHz. Its RO4350 top-layer dielectric, CPWG routing, and SMA connectors are engineered to preserve signal integrity and impedance match across this entire range, as verified in Analog Devices' published performance curves.

Can the EV1HMC349AMS8G be used for thermal testing of the HMC349AMS8G?

Yes - the EV1HMC349AMS8G includes extensive thermal design features: direct soldering of the HMC349AMS8G's exposed pad to the ground plane and a dense array of plated through vias surrounding the IC and RF traces. These enable accurate junction-to-case thermal resistance measurement (θJC = 67.1°C/W for through path) under real operating conditions.

Is the EV1HMC349AMS8G RoHS compliant?

Yes, the EV1HMC349AMS8G is explicitly listed as RoHS compliant in the official Analog Devices ordering guide and datasheet Rev. F. This compliance extends to all populated components on the board, including the HMC349AMS8G IC, SMA connectors, and 0402 capacitors.
