RF and Microwave PCB Design Controlled Impedance, Sub-GHz to mmWave
Qmax Systems provides RF and microwave PCB design from sub-GHz to mmWave bands, where the board is part of the RF circuit itself. Qmax Systems RF engineers control trace geometry, dielectric loss, via transitions, grounding, and shielding to hold insertion loss, phase stability, noise floor, and EMI compliance - across radar sensors, RF instrumentation, and wireless communication platforms.
Qmax Systems treats RF PCB layout as fundamentally an electromagnetic design problem - above a few hundred MHz, traditional digital PCB practices become insufficient. Qmax's RF engineers cover the full RF spectrum, from controlled-impedance RF layout to microwave engineering and millimeter-wave design from 24 GHz to 80 GHz, plus antenna and RF front-end integration. These designs serve 5G wireless, radar sensors, RF instrumentation, industrial RF generators, and satellite communications.
RF PCB Layout Services - Qmax delivers precision layout for single- and multi-band RF systems with controlled impedance and shielding strategies.
Microwave PCB Engineering - Microwave-frequency designs use specialized substrate selection and transition management.
mmWave PCB Design (24 GHz–80 GHz) - Qmax's RF engineers build millimeter-wave layouts for 5G, radar, and imaging systems with ultra-tight tolerances.
Antenna Integration & RF Front-End Layout - Antenna structures, matching networks, and RF front-end modules share a single PCB.
