A network of transmission lines that distributes and divides RF/microwave signals within a power divider.

Product Specifications

Technical details and manufacturing context for Transmission Line Network

Definition
The transmission line network is the core component of a power divider that physically implements the signal division function. It consists of precisely designed transmission line segments (typically microstrip, stripline, or coaxial lines) arranged in a specific topology to split an input signal into multiple output signals with controlled amplitude and phase relationships. Within the power divider, this network determines the division ratio, isolation between ports, and overall frequency response.
Working Principle
The transmission line network operates based on electromagnetic wave propagation principles. When an RF/microwave signal enters the network, it travels through the transmission line segments. The network's geometry (lengths, widths, and connections of the lines) creates specific impedance transformations and signal paths that cause the input power to be divided among the output ports according to the design specifications (e.g., equal or unequal power division). The network maintains proper impedance matching to minimize reflections and signal loss.
Common Materials
Copper, Dielectric substrate (e.g., FR4, Rogers material), Protective coating (e.g., gold plating, solder mask)

Engineering Reasoning
0.1-40 GHz
Signal attenuation exceeding 3 dB at 40 GHz due to skin effect and dielectric losses
Design Rationale: Electromagnetic wave propagation degradation from conductor surface roughness exceeding 0.1 μm RMS and substrate dielectric constant variation beyond ±0.2 at 25°C
Risk Mitigation (FMEA)
Trigger Impedance mismatch at 50 Ω interface due to manufacturing tolerance exceeding ±1%
Mode: Signal reflection causing VSWR >1.5:1 at 18 GHz
Strategy: Implement stepped-impedance matching sections with λ/4 transformers at critical junctions
Trigger Thermal expansion coefficient mismatch between alumina substrate (7.1 ppm/°C) and copper conductor (16.6 ppm/°C)
Mode: Micro-crack formation in transmission line after 1000 thermal cycles from -40°C to +85°C
Strategy: Use co-fired ceramic multilayer construction with matched CTE materials (6.5-7.5 ppm/°C range)
