Analog Devices Inc. EV1HMC547ALP3

Overview

EV1HMC547ALP3 from Analog Devices is an evaluation board for the HMC547ALP3E GaAs MMIC SPDT non-reflective switch, supporting DC–20 GHz operation with >50 dB isolation up to 5 GHz, 1.8 dB insertion loss at 10 GHz, and complementary -5/0 V control logic. It enables RF path selection in microwave radio, test instrumentation, and fiber-optic infrastructure.

For engineers reviewing the EV1HMC547ALP3 datasheet, EV1HMC547ALP3 pinout, EV1HMC547ALP3 application, or EV1HMC547ALP3 equivalent, this page delivers verified layout guidance, RF port impedance matching details, grounding requirements for QFN-16 package integration, and evaluation-ready component sourcing for high-frequency switch validation.

Technical Context

The EV1HMC547ALP3 implements a Rogers 4350-based RF evaluation PCB hosting the HMC547ALP3E in a 3×3 mm QFN-16 package, with all RF traces impedance-controlled to 50 Ω and ground vias placed adjacent to each GND pin (pins 2,4,6,8,13,15) and N/C pad (pins 1,5,9,12,16). The board integrates SMA connectors (J1–J3) for RFC, RF1, and RF2 ports and includes DC bias pins (J4–J6) and 100 Ω termination resistors (R1–R2).

It enforces strict RF grounding: the exposed paddle of the HMC547ALP3E must be soldered directly to the PCB ground plane, and all RF signal paths avoid stubs or discontinuities. The design supports full characterization of switching speed (tRISE/tFALL = 2 ns), isolation (>40 dB up to 15 GHz), and P1dB (24–29 dBm) under -40°C to +85°C operating conditions.

FAQ

What is the primary function of the EV1HMC547ALP3 evaluation board?

The EV1HMC547ALP3 evaluation board provides a fully characterized RF platform for the HMC547ALP3E SPDT switch, enabling rapid verification of insertion loss, isolation, return loss, and switching speed across DC–20 GHz. It includes calibrated SMA interfaces, proper grounding, and thermal design aligned with the device's absolute maximum ratings and MSL3 reflow profile.

Does the EV1HMC547ALP3 support both RF1 and RF2 path evaluation simultaneously?

No - the EV1HMC547ALP3 implements a single-pole double-throw configuration with dedicated RFC, RF1, and RF2 SMA connectors. It allows sequential evaluation of either RFC→RF1 or RFC→RF2 paths using complementary -5/0 V control on pins A and B, per the truth table. Simultaneous dual-path operation is not supported by the board layout or HMC547ALP3E functionality.

What are the required control voltage levels for operating the HMC547ALP3E on the EV1HMC547ALP3 board?

The EV1HMC547ALP3 requires two complementary control voltages applied to pins A and B: "High" = -5 V ±0.5 V (3 µA typical), "Low" = 0 to -0.2 V at ≤10 µA. These match the HMC547ALP3E's negative logic interface and are routed via J4–J6 DC pins. No external bias supply is needed beyond these control lines.

Can the EV1HMC547ALP3 be used for hot-switching applications at +23 dBm?

Yes - the EV1HMC547ALP3 layout supports hot-switching up to +23 dBm (per HMC547ALP3E absolute maximum rating), provided the PCB ground plane is uninterrupted beneath the device, thermal vias are fully filled, and RF connectors are properly torqued. The Rogers 4350 substrate and optimized via fence ensure stable performance under high-power transient conditions.

Is the EV1HMC547ALP3 RoHS-compliant and MSL-rated?

Yes - the EV1HMC547ALP3 uses RoHS-compliant components and follows the HMC547ALP3E's MSL3 rating (peak reflow temperature 260 °C). The board itself carries no moisture sensitivity classification, but its assembly and handling must comply with IPC/JEDEC J-STD-020 for MSL3 devices to prevent popcorning during reflow of the mounted HMC547ALP3E.
