PCB-to-Waveguide Transition Design — Microstrip Launch, Loss Budget and Manufacturing Tolerance As mmWave antenna and interconnect designs push toward W-band and beyond, more systems are combining a standard PCB with a waveguide or 3D-printed metallized waveguide structure rather than relying…
RF PCB Manufacturer for Phase-Matched, Multi-Channel Designs — What to Ask Before You Order Multi-channel RF boards — frequency synthesizer distribution, phased array feed networks, multi-channel receiver front-ends — put a demand on a PCB supplier that a single-channel RF…
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…
