Duplexer tuning optimizes wireless system performance by enabling simultaneous transmission/reception. Proper adjustment prevents signal degradation in dense networks.Technicians use vector network analyzers to adjust tuning screws while monitoring responses. The process includes frequency alignment, passband optimization, and isolation enhancement between pathways. This method requires expertise but offers precise control.Instrument-Assisted MethodsModern VNAs with tuning software provide visual feedback through Smith charts. Automated systems test multiple configurations rapidly, improving measurement accuracy and consistency. Portable versions enable precise field applications.Production vs Field TuningFactory tuning employs robotic calibration for specification compliance. Field tuning adapts to environmental conditions and site-specific requirements, using portable equipment to optimize real-world performance.•Phase alignment for carrier aggregation
•Time delay optimization for massive MIMO
•Temperature stability across operational ranges
