地砖十大品牌摘要：A compact, flat coupling, and broadband directional coupler are prented for high-power applications in the frequency band of 100 1000 MHz. The coupler is mainly compod of two compact mi-flexible coaxial cables with the length of the λ0/4 (λ0 is the free-space wavelength at the frequency of 850 MHz), four chip ceramic capacitors, and two air wound inductors that can tune the coupling coefficient. The pha inverter of the coupler is well designed and experimentally validated. The directional coupler exhibits high performance in the whole operation frequency band with low inr
tion loss (less than 0.3 dB), high directivity (more than 18 dB), and high power (up to 300 W). The amplitude imbalance of the coupling coefficient is less than 0.3 dB. The measured results exhibit good consistency with the theoretical analysis.
