It's been a long time. I was not active due to health problems. Now I'm slowly coming back. I have added a notch filter in the attached picture. This filter is produced so that the two RF systems working side by side do not interfere with each other. 1 watt rf transmitter in the 915 mhz band and 1200 mhz rf video receiver are used to avoid interference. This filter is to protect 1200mhz rf video receiver from noise from 915mhz rf transmitter. If this filter is not used, noise appears in the image. Should I do to build a pcb filter like this?

A Notch Filter is also known as a Band Stop filter or Band Reject Filter. These filters reject/attenuate signals in a specific frequency band called the stop band frequency range and pass the signals above and below this band. For example, if a Notch Filter has a stop band frequency from 1200 MHz to 1300MHz, it will pass all signals from DC to 1200 MHz and above 1300 MHz. It will only block those signals from 1200 MHz to 1300 MHz.
