Item Code:LP-MC05/06/07/10/15/20/25 0825B Features:Directional coupler commonly used for sampling the microwave signal with the given flows. Absence of the load, the directional coupler is always the 1/4-port network. Adopting the parallel Coupled lines, the coupled zone length is integer multiple comparing the fourth wavelength, and its output port is non-adjacent with the coupling port on the structure, the output phase discrepancy is 90 degrees or 180 degrees, the remaining port which is called isolation port is not output any energy theoretically.

Description
Specifications

Parametric illustrate:
Coupling: the output power of coupled port / the main-line input power when the remaining port connected with load,
Coupling loss: the power output reduction due to the coupling port, equal to the theoretical value of the main-line insertion loss, The relationship between the minimum theoretical value of the main-line insertion and coupling degree as follows:
Coupled degrees: 3 dB 5dB 7dB 10dB 15dB 20dB
The theoretical loss of main line: 3.0 dB 1.65dB 0.97dB 0.46dB 0.14dB 0.04dB
The main line loss: When each ports connected with load excluding main line, the power changes caused by load due to the coupling in the transmission system, the main line insertion loss also including two aspects: the energy coupling loss & energy dissipation loss.
