Description


Description
TE21 Monopulse Tracking Feed is a four-port device, PORT1 is a common port, it is a circular waveguide port, both transmit "SUM" channel transmission signal and receive signal, and transmission "error" channel error signal, connect with the horn when actual work. PORT1 is also a common port, its function is only for the channel transmission port, transmission "sum" channel transmission signal and receive signal. PORT3 and PORT4 are two circular polarization error signal receiving ports for the TE21 mode tracker, one of the way for the left circular polarization, the other way for the right circular polarization.
The Ka-band tracker coupled with the corresponding reflector can complete the launch and tracking functions, can play an important role in the field of satellite communications. Similar products in other bands can also be tailored to design and production.
