Rogers PCB from China — How to Verify Authentic Material and Avoid Sourcing Mistakes China is the largest manufacturing base for Rogers PCB fabrication globally, and legitimate, reliable suppliers are common — but so is quote variance wide enough that…
RF PCB Manufacturer for Mixed-Signal, High-Speed Digital Designs — What Sets Them Apart The line between RF PCB and high-speed digital PCB keeps getting thinner. RF SoCs, frequency synthesizers, and ADC/DAC boards routinely combine 50Ω single-ended RF traces with differential…
RF PCB Quality Control — AOI, TDR Sampling, Microsection and Batch Traceability RF PCB quality control differs from standard digital PCB inspection in one important way: electrical continuity is not the same as RF performance. A board can pass 100%…
RF Connector Launch PCB Design — SMA and 2.92mm Transition Rules for Minimum Return Loss The connector launch — where an RF connector transitions to a PCB microstrip or stripline trace — is one of the most common sources of…
GaN RF Power Amplifier PCB — Thermal Via Array, Ground Pad Voids and Material Selection by Power Class GaN-on-SiC RF power amplifiers pack significantly higher power density into the same package footprint as older LDMOS or GaAs devices, which shifts…
Rogers FR4 Hybrid PCB Design Guide — Bonding Film Selection, Lamination Cycles and Cost Optimization A Rogers FR4 hybrid PCB combines Rogers RF material on the layers that carry RF signal with standard FR4 on digital, power and ground layers…
