When a team selects 5G antenna PCB, it is usually solving a specific product constraint rather than buying a label. This article takes a thermal view of antenna aperture geometry, feed transitions, matching features, enclosure clearance, and reference-plane control. The project pain is a feed that is nominally 50 ohms but is detuned by housing...
When a team selects 5G PCB, it is usually solving a specific product constraint rather than buying a label. This article takes a dfm view of 5G radio-board material choices, copper geometry, controlled references, and power-to-RF partitioning. The project pain is phase drift, insertion-loss budget, thermal coupling from power amplifiers, and a stack -up that...

When a team selects 5G PCB, it is usually solving a specific product constraint rather than buying a label. This article takes a transition view of 5G radio-board material choices, copper geometry, controlled references, and power-to-RF partitioning. The project pain is phase drift, insertion-loss budget, thermal coupling from power amplifiers, and a stack-up that changes...

In a compact mmWave package, the Alumina PCB is often both circuit carrier and mechanical reference. A cavity, lid, bond window, connector, or waveguide transition can define the electromagnetic boundary more strongly than a long trace. The project risk is a datum mismatch: the electrical drawing references the board edge while the housing references the...
A wideband RF link can show unexplained phase imbalance even when both traces meet the same nominal impedance. On a PTFE PCB, the local resin-to-glass distribution, trace angle, reference-plane spacing, and connector launch can create different effective propagation paths. The project pain is usually discovered after the schematic is stable, when the pair is already...
At mmWave frequencies, the cavity, copper edge, connector launch, and antenna clearance become part of the circuit. A Ceramic PCB is often selected for its dimensional stability and integration potential, yet a cavity that is only slightly too deep or a ground fence that is interrupted by a tooling keep-out can move the resonance enough...
Table of Contents Locate the coupling path before placing vias Build a repeatable fence and reference transition Coordinate shields, connectors, and assembly access Verify the fence in DFM and first article release Dense wireless modules often pass an electrical review and still show channel-to-channel coupling after the first hardware build. The cause is usually not...
