The utility model provides a new type of high-damping isolator, which comprises a high-damping isolator body composed of an upper support plate, a lower support plate and a high-damper arranged therein. The high-damping isolator body has an omega-shaped structure. The extension section of the omega-shaped structure is provided with an antenna connection port, and the arc section is provided with a support connection port, and the antenna connection port is also provided. Anti-collision parts. When installing and using the anti-collision parts, it can prevent the radome from colliding with the body of the new high damping isolator, which will affect the use effect. The utility model overcomes the problems of antenna safety, signal instability, loss and noise disturbance under vehicle excitation, wind load and earthquake excitation. The high-damped isolator with a_-shaped structure can connect antennas in two directions and brackets in the other direction, which is suitable for bidirectional vibration isolation of signal transmission antenna, and can significantly reduce the vibration and PIM value of antenna, and maintain the antenna. The safety of antenna and the quality of signal transmission are proved.

技术介绍
众所周知,有源器件会在系统中产生非线性效应。人们已开发出多种技术来改善此类器件在设计和运行阶段的性能。容易忽视的是,无源器件也可能引入非线性效应;虽然有时相对较小,但若不加以校正,这些非线性效应可能会严重影响系统性能。PIM表示“无源交调”,它代表两个或更多信号通过一个具非线性特性的无源器件传输时产生的交调产物。机械连接部分的相互作用一般会引起非线性效应,这在两种不同金属的接合处尤为明显。实例包括:松动的电缆连接、不干净的连接器、性能糟糕的双工器或老化的天线等。无源交调在蜂窝通信行业是一个重大问题,而且非常难以排解。在蜂窝通信系统中,PIM可能引起干扰,降低接收机灵敏度,甚至完全阻塞通信。这种干扰可能影响产生它的蜂窝以及附近的其他接收机,例如,在LTE频段2中,下行链路范围是1930MHz至1990MHz,上行链路范围是1850MHz至1910MHz。若有两个分别位于1940MHz和1980MHz的发射载波从具有PIM的基站系统发射信号,则其交调会产生一个位于1900MHz ...
