Analog Devices Inc. EV1HMC244AG16

Overview

EV1HMC244AG16 from Analog Devices is an evaluation PCB designed for the HMC244AG16 GaAs MMIC SP4T non-reflective switch, supporting DC–4 GHz RF signal routing with 0.9 dB typical insertion loss at 3 GHz and 30–45 dB isolation. It integrates a 2:4 TTL/CMOS decoder requiring only two control lines and +5 V bias, enabling compact telecom infrastructure and test instrumentation designs.

For engineers reviewing the EV1HMC244AG16 datasheet, EV1HMC244AG16 pinout, EV1HMC244AG16 application, or EV1HMC244AG16 equivalent, this board provides validated RF layout, SMA connectors, 50 Ω impedance-controlled traces, exposed ground paddle soldering guidance, and direct mounting support for the HMC244AG16 in hermetic 16-lead SMT package.

Technical Context

The EV1HMC244AG16 is a dedicated evaluation platform-not a component-featuring Rogers 4350 substrate, five SMA RF connectors (J1–J5), three DC pins (J6–J8), and five 330 pF 0402 blocking capacitors (C1–C5) to interface with the HMC244AG16's DC-coupled RF ports. All ground leads and the exposed metal paddle are routed to a continuous RF ground plane per RF design best practices.

It implements the exact biasing and control conditions specified for the HMC244AG16: +5 V ±10% on Pin 6 (Vdd), TTL-compatible logic levels on Pins 7 (B) and 8 (A), and mandatory grounding of Pins 1,3,5,10,12,13,14,16 plus the bottom paddle. No onboard voltage regulation or level-shifting is included.

FAQ

What is the EV1HMC244AG16 used for?

The EV1HMC244AG16 is an evaluation PCB built exclusively for the HMC244AG16 SP4T GaAs MMIC switch. It enables rapid RF performance verification-including insertion loss, isolation, and switching speed-under real-world bias and control conditions. Engineers use the EV1HMC244AG16 to validate layout practices, measure S-parameters, and integrate the HMC244AG16 into systems operating from DC to 4 GHz without custom PCB spin.

Does the EV1HMC244AG16 include the HMC244AG16 IC?

Yes, the EV1HMC244AG16 evaluation PCB includes one mounted HMC244AG16 IC in its 16-lead hermetic glass/metal package. The board is shipped fully assembled with U1 populated, SMA connectors installed, and all five 330 pF blocking capacitors soldered-ready for immediate RF testing upon power-up and control signal application.

What are the required control signals for the EV1HMC244AG16?

The EV1HMC244AG16 requires two TTL/CMOS-compatible digital control inputs (A and B, applied via J7 and J8) and a single +5 V ±10% supply (applied via J6) to operate the onboard HMC244AG16. These match the truth table in the HMC244AG16 datasheet: Low/Low selects RF1, High/Low selects RF2, Low/High selects RF3, and High/High selects RF4.

Can the EV1HMC244AG16 be used with 3 V logic or supply?

No-the EV1HMC244AG16 is configured for +5 V operation as specified for the HMC244AG16's Vdd pin and TTL-compatible control interface. While the HMC244AG16 itself supports +3 V supply per its datasheet, the EV1HMC244AG16 board lacks level-shifting circuitry or dual-supply routing; using 3 V would violate the board's validated bias architecture and risk incomplete switching or degraded RF performance.

Is the EV1HMC244AG16 RoHS compliant?

Yes, the EV1HMC244AG16 evaluation PCB conforms to RoHS Directive 2011/65/EU. All components-including the HMC244AG16 IC, SMA connectors, 330 pF capacitors, and Rogers 4350 substrate-are lead-free and halogen-free. Analog Devices certifies full compliance for this board in its official product documentation and material declarations.
