分布式信号覆盖增益器

The invention relates to a distributed signal covering gainer in wireless signal transmission field. It is composed of two types of gainers: same frequency signal covering gainer and different frequency covering gainer, where their input and output antennas are composed in the same rectangular coplanar PCB socket, the same frequency signal covering gainer is a basic signal amplifying circuit, basic which is common mode rejection signal amplifying circuit or compensatory circuit signal amplifying circuit, and the different frequency covering gainer is variable frequency gain signal amplifying circuit. Its advantages: it can improve the problem of existing signal covering blind spots and create a good effect of covering and extending signals by a lower price; and can solve the limitations of transmission distance and covering ability of current wireless signals.
