Satellite PCB radiation design for low-Earth-orbit avionics is often reviewed too late as a materials choice. The difficult question is not whether a board can route a signal; it is whether the dielectric, copper stack, enclosure bond, and return current still behave predictably after radiation exposure, thermal cycling, launch handling, and repeated engineering changes. A...
For Satellite PCB launch design, a Ku/Ka payload can meet its schematic targets and still lose margin at the board edge. The connector, launch pad, reference plane, via field, and enclosure datum form one electromagnetic interface. The Satellite PCB release must hold that board-to-enclosure datum constant across design and manufacturing. At 30 GHz, even a...
Thermal drift is an electrical problem when a microwave board moves enough to change trace geometry, connector alignment, or plated-hole stress. This article treats RF-35 PCB as a production material choice and focuses on the thermal-mechanical controls that keep a high-frequency design repeatable from panel build through assembly. Taconic RF-35 typical property tables report a...
Reliable RF transitions are often lost at the connector, launch, or layer change rather than in the long transmission line. This guide shows how an RO4350B PCB project can use via fences, reference-plane continuity, and fabrication controls to protect return current. It is an engineering design method, not a claimed KKPCB customer result. Why the...
Engineering intent. High-power RF modules combine heat, current, and microwave loss in a small area. This article presents a practical workflow for using an RO3003 PCB as part of a thermal-aware RF module. It is a design guide, not a customer case study or a measured KKPCB result. RO3003 is a ceramic-filled PTFE laminate in...
Engineering intent. A 77 GHz radar front end is sensitive to the geometry between the antenna elements, feed transitions, and transceiver. This article explains how to plan a RO3003 PCB stackup for that path. It is a conceptual design workflow, not a customer case study or a measured production result. RO3003 is a ceramic-filled PTFE...
Engineering intent. A phased array can lose beam accuracy when equal-looking traces have different electrical lengths or transitions. This article explains how to plan an RO3003 PCB feed network for a conceptual phased-array module. It separates layout targets from measured production data and does not claim a KKPCB customer case study. RO3003 belongs to the...
A GNSS module PCB is often treated as a simple carrier for a receiver module, antenna connector, and power supply. That view misses the part of the board that most often determines whether the receiver sees a usable signal: the path from the antenna to the module input. The layout must preserve the intended transmission-line...
High-frequency PCBs (Printed Circuit Boards) are critical components in modern wireless communication systems. They handle RF (Radio Frequency) signals that range from 300 MHz to 300 GHz, a spectrum used by technologies like 5G, IoT devices, radar systems, and satellite communications. These signals need to travel long distances without losing power or clarity, which is where high-frequency PCBs play...
As RF, microwave, and high-speed communication technologies continue to evolve, partnering with a reliable high frequency PCB OEM is critical for companies seeking consistent performance, stable quality, and scalable manufacturing. High frequency PCBs operate at GHz and millimeter-wave ranges, where even small variations in materials or processes can significantly impact signal integrity. This article explains...
