Analog Devices Inc. EVAL01-HMC197B

Overview

EVAL01-HMC197B from Analog Devices is an evaluation board designed to characterize the HMC197BE GaAs MMIC SPDT switch in SOT-26 package, supporting DC–3 GHz RF signal routing with 0.4 dB typical insertion loss at 1 GHz and +59 dBm input IP3. It enables rapid validation of RF front-end switching in ISM-band transceivers, portable wireless modules, and MMDS systems.

For engineers reviewing the EVAL01-HMC197B datasheet, EVAL01-HMC197B pinout, EVAL01-HMC197B application, or EVAL01-HMC197B equivalent, this board provides a production-representative RF layout with SMA connectors, DC blocking capacitors, and verified 50 Ω impedance control - critical for evaluating switch performance under real-world bias, power, and thermal conditions.

Technical Context

The EVAL01-HMC197B implements a fully assembled, RF-optimized test platform for the HMC197BE SPDT switch, featuring three SMA RF ports (RFC, RF1, RF2), dual CMOS/TTL-compatible control inputs (A/B), and on-board 1 kΩ pull-up resistors. It uses Rogers 4350 substrate for stable high-frequency performance and includes 330 pF 0603 DC-blocking capacitors on all RF paths.

Control logic follows the HMC197BE truth table: A=0 V / B=+3–8 V selects RF→RF1 path; A=+3–8 V / B=0 V selects RF→RF2 path. The board requires external +3 V to +8 V DC supplies for control and supports hot-switching limits up to +20 dBm (Vctl = +5 V) per Analog Devices' absolute maximum guidance.

FAQ

What is the primary purpose of the EVAL01-HMC197B evaluation board?

The EVAL01-HMC197B evaluation board is a ready-to-use RF test platform for characterizing the HMC197BE SPDT switch. It provides calibrated SMA interfaces, proper 50 Ω impedance routing, and verified DC biasing to measure insertion loss, isolation, and switching speed across DC–3 GHz - directly supporting design validation before custom PCB spin.

Does the EVAL01-HMC197B include the HMC197BE device mounted?

Yes, the EVAL01-HMC197B includes the HMC197BE GaAs MMIC SPDT switch (SOT-26 package) pre-mounted and soldered onto the Rogers 4350 PCB. The board ships fully assembled with all passive components, SMA connectors, and pull-up resistors installed per the official Analog Devices evaluation schematic.

What control voltage ranges are supported by the EVAL01-HMC197B for the HMC197BE?

The EVAL01-HMC197B supports HMC197BE control voltages from 0/+3 V to 0/+8 V on pins A and B, matching the device's specified operating range. On-board 1 kΩ resistors enable direct connection to CMOS or TTL logic families without additional level-shifting circuitry.

Can the EVAL01-HMC197B be used for power-handling validation of the HMC197BE?

Yes, but with strict adherence to Analog Devices' guidelines: do not operate the HMC197BE beyond +20 dBm during hot switching (Vctl = +5 V), and avoid 1 dB compression above +31 dBm. The EVAL01-HMC197B includes DC-blocking capacitors on all RF ports to support safe high-power testing within these limits.

Is the EVAL01-HMC197B RoHS-compliant and MSL-rated?

Yes - the EVAL01-HMC197B uses RoHS-compliant materials throughout, including the HMC197BE (MSL1, peak reflow 260 °C) and all passives. The Rogers 4350 substrate, SMA connectors, and 0603/0402 components meet JEDEC MSL-1 handling requirements and full RoHS Directive 2011/65/EU compliance.
