Successful PCB design requires finding a balance between performance, manufacturability, and solvability. This design from Abaco Systems is a great example of what that looks like in action. The four engineers who collaborated to create this high-density PCB were challenged to design for future variants, to meet tight high-speed constraints, and to address complex signal and power integrity challenges. They responded by utilizing dense placement and routing to produce this impressive 18-layer board in Xpedition. #PCBDesign #ElectricalEngineering #PCB

𝗧𝗵𝗲 𝗥&𝗦 𝗟𝗮𝗯 - 𝗕𝗮𝗻𝗱𝘄𝗶𝗱𝘁𝗵 𝗼𝗻 𝗮 𝗦𝗰𝗼𝗽𝗲 💡 Ever get a measurement that just doesn’t seem right? You're looking at a signal, it appears accurate, however, something's off in your calculations or design? 🧐 Often, the culprit isn’t the circuit itself, but how accurately you’re seeing it. Bandwidth on your oscilloscope is crucial for signal fidelity. If your scope’s bandwidth is too low, you’ll miss high-frequency components and see a distorted representation of the true signal. This video dives into how bandwidth impacts a sine wave display, showing you the visual changes as you sweep the frequency. It’s a great way to understand the limitations of your equipment and avoid misinterpretations. Watch now to get a clearer picture! Find out more 👉 https://lnkd.in/gkwpUVft

𝑯𝒐𝒘 𝒕𝒐 𝑹𝒆𝒂𝒅 𝒂 𝑺𝒎𝒊𝒕𝒉 𝑪𝒉𝒂𝒓𝒕 𝒇𝒐𝒓 𝑴𝒖𝒍𝒕𝒊-𝑷𝒐𝒓𝒕 𝑨𝒏𝒕𝒆𝒏𝒏𝒂𝒔? You’ve probably learned the Smith Chart as a single-port tool, plot S₁₁, check matching and move on. But once you step into MIMO, phased arrays or compact dual-element antennas, S₁₁ alone stops telling the truth. Multi-port antennas interact, detune each other and shift impedance in ways that only show up when you read multiple Smith loops together. The chart doesn’t get harder, it just becomes more honest. 1. Why Smith Charts Still Matter for Multi-Port Antennas? Inside every multi-port antenna, each radiator affects the others through mutual coupling. This interaction changes the effective impedance at every port even if that port isn’t transmitting. The Smith Chart captures these changes instantly, loops stretch, shift or bend when another port comes alive. It becomes a visual diagnostic tool showing how each element behaves not in isolation but in its real environment. 2. What You’re Actually Looking For? A multi-port Smith Chart isn’t one curve, it’s a set of curves. S₁₁ shows how Port 1 is matched, S₂₂ shows Port 2’s behavior and S₁₂/S₂₁ reveal how the ports influence each other. When coupling increases, the matching loops don’t stay stable, they distort. Those distortions tell you if bandwidth shrinks, if detuning occurs or if your “perfect” isolated-element simulation is lying. The beauty of the chart is that all this information appears without needing complex math. 3. Why Designers Care? In MIMO phones, phased arrays and cross-polarized antennas, performance collapses when Smith trajectories drift. Beam steering becomes unstable, bandwidth decreases and isolation drops whenever mutual coupling pushes impedance off the sweet spot. Designers fix this with decoupling networks, neutralization lines or ground-slot techniques, all of which aim to reshape the Smith loops into cleaner, more stable curves. A multi-port antenna is only as good as its worst-behaving Smith trace. 4. Critical Formulas: a) Impedance from S-parameters: → Z = Z₀ (1 + S) / (1 − S) b) Ideal matching point (50 Ω): → Center of the Smith Chart c) Coupling impact on impedance: → Strong S₂₁ causes S₁₁ / S₂₂ loops to shift outward d) Stability indicator: → Minimal loop movement = lower coupling and better isolation 5. Real-World Examples: - In smartphone MIMO antennas, a hand detuning Port 1 immediately shifts the S₂₂ loop, revealing coupling you can’t see from S₁₁ alone. - In cross-polarized base-station antennas, symmetric S₁₁/S₂₂ loops confirm stable polarization performance. Th Smith Chart below shows how the antenna’s impedance traces move across frequency, revealing both matching quality and reactive behavior for its dual-band operation. The red loops illustrate how each band shifts across the chart, highlighting where VSWR ≤ 2 is achieved and where detuning or strong reactance appears. #SmithChart #MIMO #SParameters #PhDResearch

📡 Antenna Gain vs Beamwidth: A Common Misunderstanding Ever seen a system with impressive antenna gain… but unstable links, constant realignment, or unexpected disconnection? That’s usually not a power problem. It’s a beamwidth problem. 🎯 Think of Antennas Like Flashlights • High gain / narrow beam = laser pointer 🔦  Long reach, sharp focus — but even a small movement misses the target. • Low gain / wide beam = floodlight 💡  Shorter reach, wider coverage — but much easier to stay connected. 👉The rule of thumb: More gain → narrower beam → higher precision required 🔬 What Gain Really Means • It concentrates energy in a preferred direction • That concentration is paid for with reduced angular coverage 📐 What Beamwidth Tells You • How wide the antenna “sees” • How much misalignment, motion, or vibration your link can survive ⚙️Real-World Engineering Trade-offs High Gain / Narrow Beam • Long range, focused coverage • Requires precise pointing • Low tolerance to movement • Strong interference rejection Low Gain / Wide Beam • Broad coverage, easier to maintain • Tolerates movement and misalignment • Quick and simple setup • More exposed to interference ⚖️ The Engineering Truth High gain doesn’t eliminate system challenges — it shifts them from RF design to mechanical stability and pointing accuracy. The right antenna isn’t the strongest one — it’s the one your system can realistically support. We have antennas built for real operating conditions. Feel free to reach out if you’d like to discuss your link requirements. #KINGSAT #AntennaGain #Beamwidth #NTN #Satcom #RFEngineering #MicrowaveEngineering #WirelessTechnology #Microwave

Dolby Laboratories joins Avanci 4G, 5G as licensor Dolby Laboratories is now listed as a licensor on both of Avanci’s 4G and 5G Vehicle programs. The web archive indicates that it signed up to each program as a licensor between October 10 and today. Avanci Vehicle 4G now has over 60 licensors and 45 licensees, while the 5G program has 85 licensors and 38 licensees. The move is unexpected, given Dolby’s already significant role in other patent pools. The company not only operates as a licensor in patent pools such as Access Advance LLC’s Video Distribution patent pool, and HEVC and VVC programs, Sisvel’s VP9, AV1, and Cellular IoT programs, and Vectis IP in its Opus program, but it is also a majority stockholder and licensor in Via Licensing Alliance, which it co-owns with Philips and Mitsubishi. Furthermore, Dolby holds a minority ownership interest in Access Advance. https://lnkd.in/eM8G4qi8
