Miniaturized Ku-band ODU module

Abstract

The invention discloses a miniaturized Ku-band ODU (Out-Door Unit) module, which includes a transmitting channel module and a receiving channel module. The transmitting channel module includes a firstbox which is divided into a first upper cavity body and a first lower cavity body separated from each other. The first upper cavity body is internally provided with a first intermediate frequency cavity, a first radio frequency cavity, a first power cavity and a first cavity filter. The first lower cavity body is internally provided with a first local oscillation circuit which is connected to thefirst radio frequency cavity through a first insulator and a first hole-containing micro-strip line. The receiving channel module includes a second box which is divided into a second upper cavity body and a second lower cavity body separated from each other. The second upper cavity body is internally provided with a second cavity filter, a second radio frequency cavity, a second intermediate frequency cavity and a second power cavity. The second lower cavity body is internally provided with a second local oscillation circuit which is connected to the second radio frequency cavity through a second insulator and a second hole-containing micro-strip line. The ODU module has the advantages of small size, low power consumption, stability, reliability and applicability to a wide frequency bandrange.

Description

technical field [0001] The invention belongs to the technical field of communication, in particular to a miniaturized Ku frequency band ODU module. Background technique [0002] In satellite communication equipment, ODU (Out-door Unit) refers to the outdoor unit, mainly including frequency conversion and power amplification, which can be divided into transmission channel and reception channel. The transmission channel usually refers to BUC (Block Up-Converter), It is an up-conversion RF power amplifier, and the receiving channel mainly refers to LNB (Low Noise Block down-converter), that is, low noise amplifier and frequency converter. [0003] In spaceborne communication equipment, due to space constraints, ODU mainly appears in the form of components, with standardized interfaces and volume weight. In the prior art, for the ODU module in the ku frequency band, there are large volume, heavy weight, and many external interfaces, unreliable working performance, and relativel...
