C-band dual polarization dual local oscillator single output high-frequency head (equipped with a three ring feeding plate), horizontal polarization and vertical polarization do not interfere with each other, high gain, stable and reliable, engineering specific.

Whether it is a C-band satellite signal or a Ku band satellite signal, frequency conversion processing is required on the high-frequency head. After frequency conversion, all intermediate frequency signals in the range of 950-2150 (MHz) are output. Due to the antenna focusing on the high-frequency head feed cavity, there are both horizontally polarized and vertically polarized signals. A switcher has been designed in the single local oscillator dual polarized high-frequency head. When the receiver provides 18V voltage to the high-frequency head through a coaxial cable, this switcher allows the horizontally polarized signal to pass through, then enter the amplification and frequency conversion circuit and finally input the receiver. When the receiver provides 13V voltage to the high-frequency head through a coaxial cable, this switcher allows the vertically polarized signal to pass through. Polarized signals pass through, which is why there is a "polarization" design option on the interface of the receiver. This single local oscillator dual polarization high-frequency head can only output one polarized satellite signal at a certain moment, and two receivers can only receive programs with the same polarization at the same time using this single local oscillator high-frequency head. Now let's talk about the dual local oscillator single output C-band high-frequency head that needs to be used for two machines to receive without affecting each other. There is no polarization switch mentioned above in this type of high-frequency head. It is designed with two independent frequency conversion circuits, which respectively and simultaneously amplify the horizontal polarization and vertical polarization satellite signals. Then, they are mixed together and input into the receiver through a coaxial cable. Since the frequency range of the C-band horizontal polarization and vertical polarization signals is in the 3.7-4.2 (Hz) range, and these two circuits work simultaneously, in order to avoid the phenomenon of two sets of programs with the same frequency or extremely small frequency difference entering the receiver after frequency conversion of the two polarized signals (which is chaotic), people use the dual local oscillator. The single output C-band high-frequency head has two local oscillator frequencies, one designed as 5150MHz and the other designed as 5750MHz. This makes the frequency of the two polarized programs "well water does not invade river water". Horizontal 3.7-4.2 (GHz) becomes a signal of 1450-950MHz after 5150MHz conversion, and vertical 3.7-4.2 (GHz) becomes a signal of 2050-1050MHz after 5750MHz conversion.
