High-frequency signal integrity is the defining performance factor in modern 5G mmWave antenna systems, where routing density, insertion loss, and phase stability determine overall RF efficiency. As 5G architectures transition to 26–29 GHz, 37–40 GHz, and 60 GHz mmWave bands, the electrical behavior of the Low Loss PCB stackup becomes just as important as the...
High-density RF modules used in 5G radios, SATCOM terminals, phased-array beamformers, and mmWave front-end units are increasingly constrained by thermal stress, EMI coupling, and insertion loss. As operating frequencies push beyond 10–40 GHz, traditional FR-4 structures can no longer maintain stable impedance, consistent dielectric behavior, or low-loss routing. This is where Low Loss PCB materials—such...
The shift toward 5G FR2, advanced radar, high-resolution sensing and satellite communication has placed intense performance pressure on mmWave Module PCB design. At frequencies from 24 GHz to 86 GHz, the PCB is no longer a passive carrier—it becomes an active RF component whose materials, stackup, via transitions and routing geometries directly dictate performance. A...
Modern wireless systems—from 5G radio units and phased-array antenna modules to automotive radar and satellite communication terminals—demand PCBs that deliver high RF power handling, exceptional phase stability, and ultra-low loss. As antenna modules continue to shrink while operating at higher frequencies, selecting the correct laminate becomes a mission-critical design decision. Among all mid-frequency RF substrates,...
Advanced driver-assistance systems (ADAS) rely heavily on multi-sensor fusion, where radar, LiDAR, ultrasonic sensing, and camera modules continuously exchange high-frequency data. To maintain real-time performance and safety-critical reliability, the ADAS PCB must deliver low-loss signal transmission, stable dielectric behavior, and tight impedance control under prolonged automotive thermal and vibration stress. High-frequency ADAS RF chains—particularly 24...
5G mmWave base station modules require high-frequency RF interconnects that maintain low insertion loss, phase stability, and impedance accuracy under high power and dense component placement. Thermal hotspots and EMI in multilayer architectures can severely degrade link performance and reduce overall throughput. RO4350B PCB laminates (Dk = 3.48 ± 0.02, Df = 0.0037 @10 GHz)...
Laptop Wi-Fi 6/7 systems operate with extremely tight RF tolerances: multi-band OFDMA, 4096-QAM, and Multi-Link Operation demand predictable impedance, low-loss transmission, and strict phase alignment. Traditional FR-4 substrates introduce thermal drift, inconsistent Dk, and elevated loss, making them insufficient for 6 GHz high-band routing. RO4350B PCBs solve these issues by combining ceramic-filled hydrocarbon dielectric stability...
RO4350B PCB materials are widely deployed in 5G smartphone RF front-end modules because they provide a balanced dielectric profile, low-loss characteristics, and stable RF transmission up to sub-6 GHz and selected mmWave bands. Modern antenna arrays, PA/LPF modules, LNA chains, and tunable impedance networks face stringent constraints in signal integrity, power density, EMI coupling, and...
Ensuring Consistent RF Performance Through KKPCB’s Validation Process In high-frequency applications—from 77 GHz automotive radar to 28 GHz 5G antenna arrays—the long-term stability and reliability of the PCB material determine system integrity more than any single design parameter. Among numerous high-frequency laminates, Rogers RO4350B PCB stands out for its balance of low dielectric loss,...
