Abstract

The invention discloses scatter communication high frequency equipment for full-band operations. The scatter communication high frequency equipment comprises a frequency converter, a power amplifier, a limiting low noise amplifier, a first circulator, a second circulator, a coupler and a loader, a transmitting channel frequency conversion filter, a receiving channel frequency conversion filter, a transmitting channel duplexing filter, a receiving channel duplexing filter and a monitoring unit. An intermediate frequency input signal is firstly up-converted to a radio frequency signal through the frequency converter, the radio frequency signal is subjected to frequency selection through the transmitting channel frequency conversion filter and then is sent to the power amplifier, the power amplifier carries out power amplification for the radio frequency signal that is subjected to frequency selection, and a high-power signal output by the power amplifier is fed to an antenna through the transmitting channel duplexing filter and then is emitted through the antenna; and a radio frequency small signal received from the antenna is firstly subjected to frequency selection through the receiving channel duplexing filter, then enters the limiting low noise amplifier to perform low-noise limiting amplification, is filtered by the receiving channel frequency conversion filter, then enters a down-conversion area of the frequency converter to be converted to an intermediate frequency signal, and then is transmitted to a low-frequency unit after being amplified to an appropriate level.

Description

technical field [0001] The invention relates to a high-frequency device for scattering communication in the field of communication, which can be continuously tuned in the range of 4400MHz to 5000MHz, can transmit 100W continuous wave power, and supports 35MHz signal bandwidth, and is especially suitable for complex networking and large-scale applications. Scattered communication system for capacity, long-distance signal transmission. Background technique [0002] At present, high-frequency equipment for scattering communication has been widely used in the C-band. With the development of the times, the requirements for high-frequency equipment are getting higher and higher, such as free networking, small size, high transmission power, and low noise figure. If a fixed-section waveguide duplexer is used inside the high-frequency equipment, high-power transmission signals can be completed, and the noise figure can also be small, but the networking function cannot be completed, ...
