Analog Devices Inc. EV1HMC245AQS16

Overview

EV1HMC245AQS16 from Analog Devices is an evaluation PCB designed for the HMC245AQS16E GaAs MMIC SP3T non-reflective RF switch, supporting DC–3.5 GHz operation with 0.7 dB typical insertion loss at 2.0 GHz, 40 dB isolation at 1.0 GHz, and TTL/CMOS-compatible 2-line control. It enables rapid prototyping of RF front-end switching in basestation infrastructure and test equipment.

For engineers reviewing the EV1HMC245AQS16 datasheet, EV1HMC245AQS16 pinout, EV1HMC245AQS16 application, or EV1HMC245AQS16 equivalent, this board provides validated RF layout, SMA connectors (J1–J4), DC bias headers (J5–J8), and integrated 100 pF/10 kPf decoupling to accelerate characterization of the HMC245AQS16E switch under real-world impedance-matched conditions.

Technical Context

The EV1HMC245AQS16 is a dedicated evaluation platform-not an IC-featuring Rogers 4350 substrate for stable high-frequency performance, 50 Ω microstrip routing to all RF ports (RFC, RF1–RF3), and direct ground-plane connections for all package GND pins (pins 2–5, 7, 11, 13, 15, 16) of the mounted HMC245AQS16E. It implements the exact biasing and control interface specified in the switch's truth table (A/B logic) and absolute maximum ratings.

Designed exclusively for the HMC245AQS16E in 16-lead QSOP (RQ-16), the board includes four 0402 100 pF RF decoupling capacitors (C1–C4) and one 0603 10 kPf bulk capacitor (C5), matching the recommended power supply filtering per Analog Devices' application guidance. No on-board active components or signal conditioning are present-only passive RF interconnect and bias delivery.

FAQ

What is the EV1HMC245AQS16 used for?

The EV1HMC245AQS16 is an evaluation PCB specifically built to characterize the HMC245AQS16E SP3T RF switch. It provides SMA-connected RF paths, proper 50 Ω routing, and verified decoupling to enable accurate insertion loss, isolation, and switching speed measurements without custom layout effort. Engineers use EV1HMC245AQS16 to validate switch behavior in real system-level conditions before integration.

Does the EV1HMC245AQS16 include the HMC245AQS16E device?

Yes, the EV1HMC245AQS16 evaluation PCB ships with the HMC245AQS16E GaAs MMIC SP3T switch pre-mounted in its 16-lead QSOP package. The board is delivered fully assembled with all passive components (C1–C5), SMA connectors (J1–J4), and DC headers (J5–J8) installed and tested per Analog Devices' reference design.

What RF frequency range does the EV1HMC245AQS16 support?

The EV1HMC245AQS16 supports the full operational bandwidth of the HMC245AQS16E: DC to 3.5 GHz. Its Rogers 4350 substrate, controlled-impedance 50 Ω traces, and optimized grounding ensure minimal dispersion and return loss degradation across this range, enabling reliable S-parameter measurements up to 4 GHz.

Can the EV1HMC245AQS16 be used with other SP3T switches?

No-the EV1HMC245AQS16 is mechanically and electrically tailored exclusively for the HMC245AQS16E in RQ-16 (16-lead QSOP) packaging. Pin pitch, ground via placement, RF pad geometry, and decoupling network values are specific to that device. Using it with other switches-even functionally similar ones-will compromise RF performance and may damage the board or device.

How do I power and control the HMC245AQS16E on the EV1HMC245AQS16?

Apply +5 Vdc ±10% to the Vdd pin (J5) and connect digital control signals A and B (J7 and J6) using TTL/CMOS logic levels per the truth table: Low/Low → RF1, High/Low → RF2, Low/High → RF3, High/High → All Off. Ground (J8) must be tied to system ground. The EV1HMC245AQS16 provides no onboard regulation or level-shifting-it relies on external clean supplies as specified for the HMC245AQS16E.
