A PCB transmission line is a conductive pathway on a printed circuit board designed to carry high-frequency signals with controlled impedance and minimal loss.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Impedance | 50 Ω or 75 Ω (common values) | |
| Trace Width | 0.1 mm to 0.5 mm (typical) | |
| Insertion Loss | < 0.5 dB/inch at 1 GHz | |
| Frequency Range | Up to 10 GHz+ | |
| Dielectric Constant | 4.3 (FR-4) to 3.38 (Rogers) | |
| Substrate Thickness | 0.8 mm to 1.6 mm |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is used in the following industrial products
A circuit network that matches the output impedance of a Low-Noise Amplifier (LNA) to the subsequent stage or load impedance to maximize power transfer and minimize signal reflection.
Circuit component that interfaces the transmitter output with the antenna while optimizing impedance matching for maximum power transfer and signal integrity.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Manufacturer profiles associated with PCB Transmission Line.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
It ensures efficient power transfer by matching impedances between components, reducing signal reflection and loss in high-frequency applications like RF amplifiers.
Impedance is controlled by adjusting trace geometry (width, thickness), dielectric properties of the substrate, and distance to ground planes, following design standards like IPC-2141A.
