Technical Context

The EV1HMC1118LP3D is a dedicated evaluation platform for the HMC1118 SPDT switch, built on Rogers 4350B substrate to preserve RF integrity across 9 kHz–13 GHz. It integrates SMA connectors (J1–J3), test points (TP1–TP5), and 100 pF DC-blocking capacitors (C1, C5) aligned with the HMC1118's dc-coupled 50 Ω RF ports and dual-supply operation (VDD = +3.3 V, VSS = −2.5 V).

Board layout follows strict RF design rules: 50 Ω controlled-impedance traces, direct grounding of the HMC1118's exposed pad and all GND pins to the ground plane, and minimized parasitic coupling - ensuring accurate characterization of insertion loss, isolation, P1dB (37 dBm typ), and IIP3 (62 dBm typ) under real-world bias and thermal conditions.

FAQ

What is the EV1HMC1118LP3D used for?

The EV1HMC1118LP3D is an evaluation board for the HMC1118 SPDT RF switch, enabling engineers to validate its 9 kHz–13 GHz performance in real circuits. It provides SMA interfaces, calibrated 50 Ω traces, and proper grounding to measure insertion loss, isolation, and switching speed - critical before integrating the HMC1118 into final designs like microwave radios or test equipment.

Does the EV1HMC1118LP3D include the HMC1118 device?

Yes, the EV1HMC1118LP3D includes the HMC1118LP3DE device mounted on the board - a 3 mm × 3 mm, 16-lead LFCSP packaged version of the switch. The board is shipped fully assembled with U1 populated, allowing immediate RF testing without additional component sourcing or soldering.

What PCB material is used for the EV1HMC1118LP3D?

The EV1HMC1118LP3D uses Rogers 4350B laminate (PCB part number 600-01012-00-1), selected for stable dielectric constant (ε_r ≈ 3.48), low loss tangent (tan δ = 0.0037), and consistent 50 Ω impedance control up to 13 GHz - essential for preserving the HMC1118's broadband RF performance.

Can the EV1HMC1118LP3D operate with a single positive supply?

No - the EV1HMC1118LP3D is configured to match the HMC1118's recommended dual-supply operation: +3.3 V on VDD and −2.5 V on VSS. While the HMC1118 can function with VSS tied to ground, the evaluation board implements the full dual-rail bias to ensure specified P1dB (37 dBm), IIP3 (62 dBm), and isolation performance per the Rev. A datasheet.

How are the RF ports terminated on the EV1HMC1118LP3D?

The EV1HMC1118LP3D routes RFC, RF1, and RF2 to SMA connectors (J1–J3) with no internal termination - all ports are dc-coupled and require external 50 Ω loads during off-state measurement. The board includes 100 pF dc-blocking capacitors (C1, C5) on RF paths to prevent dc shorts while maintaining broadband RF continuity.
