Signal generator with adjustable phase

Abstract

The invention discloses a signal generator with an adjustable phase. The signal generator comprises a housing, a circuit board disposed in the housing, and an antenna disposed on the housing. The circuit board comprises a signal generating board and a phase adjusting device. The phase adjusting device is coupled to the signal generating board. The phase adjusting device includes a casing and a phase adjusting assembly disposed in the casing. The casing has a hollow cylindrical shape with both ends closed. The phase adjusting assembly includes a main shaft coil and a phase adjusting coil. In the signal generator with the adjustable phase according to the invention, through the arrangement of the casing, the main shaft coil and the phase adjusting coil, the phase adjustment can be effectively realized by utilizing the mutual induction of the main shaft coil and the phase adjusting coil. Compared with the prior art that adopts the method of software adjustment, the signal generator with the adjustable phase has a simple overall structure and is easy to implement.

[0002] With the rapid development of radio communication technology, the existing communication spectrum is gradually insufficient. Therefore, the existing technology adopts the communication method of cognitive radio to make full use of the temporarily unused idle spectrum for communication to solve the problem of The problem of insufficient spectrum resources in the process of wireless communication

[0003] In the process of wireless communication, the signal generator and the receiver are very important. The quality of the communication between the signal generator and the receiver will directly affect the communication quality of the whole radio, and the communication between the signal generator and the receiver The matching degree of the transmission signal phase directly affects the transmission quality of the signal, and the signal phase of the existing signal generator is fixed, so when there is an inequity between the phase of the signal generator and the receiver, it will lead to signal inconsistency. There will be mutual cancellation between them, which will lead to the problem of poor communication quality. However, the existing phase adjustment equipment adopts circuit or software adjustment, so its operation process is very complicated and cannot be used by ordinary users.
