The VSWR，Return loss,Insertion loss,Isolation,coupling,Directivity,Frequency Sensitivity of the coupler, calculation formula
For a directional coupler, these parameters characterize how well it samples power flowing in one direction while rejecting the other. Here are the standard calculation formulas:Read more -
The VSWR，Return loss,Insertion loss,Isolation,Phase balance,Amplitude balance of the bridge, calculation formula
In RF and microwave engineering, a “bridge” usually refers to a directional bridge (or return loss bridge). Think of it as a specialized type of directional coupler used to measure how well a device is matched to a system . Here are the key formulas for its parameters:Read more -

Fabrication of front-end filters
Without a filter in the RF front end, the receiving effect will be greatly reduced. How big is the discount? In general, with good antennas, the distance will be at least 2 times worse. Also, the higher the antenna, the worse the reception! Why is that? Because today's s...Read more
