Medium Power Digital Repeater
Introduction
J3D digital repeater are designed for installer and operaters It is with SDR technology, the system can easily adjust the sub-band and the channels to adapt the requirement using software without any change on the hardware.Digital ADC \ DAC plus FPGA is used as the main chip design.
The digital filters enable repeaters to have over 60dBc out of band rejection.
