dual band digital repeater has a wide range of applications in RF/microwave systems, such as time multiplexers, time division channel selection, pulse modulation, transceiver switches, beam adjustment, etc. The index of the switch is relatively simple. The on-off loss is as small as possible, and the turn-off loss is as large as possible. The frequency band and power meet the system requirements.

Devices that make up the dual band digital repeater are ferrites, PIN tubes, FeTs, or BJTS. Ferrite and PIN are classic switching devices. Table 1 shows the performance comparison of the two devices. Ferrite is characterized by high power and low loss, while PIN is characterized by high speed and low cost. Fets or BJTS have gain and have become the main devices of low and medium power switches. dual band digital repeater for a variety of devices has its place.

The principle of ferrite switching is to change the direction of the bias magnetic field, realize the change of the permeability, change the transmission constant of the signal, in order to achieve the purpose of switching.
