机电横杆开关矩阵: CB-Series
宽带、高频率和高功率卫星通信applications, Dow-Key® understands the need of switching between more complex test setups may be require. The CB-series crossbar matrix is an excellent choice that allows the user to switch between multiple input and output ports; switch an input signal to any unique output port at a given time. The largest standard configuration is up to 12 inputs by 12 outputs and operates to 18 GHz. Larger systems and/or solutions with higher frequency options are also available.

卫星Integrated 19 Rack Solutions
For extreme complex and high density switching needs, Dow-Key® has both the expertise and the capability to custom design full rack SATCOM systems with complex switching requirements. For instance, C-band 32×64 solution, model 5096, is built using two 16×64 input modules and four 32×16 modules together with a controller unit, touch screen and a fan controller unit to keep the system cool. A more sophisticated solution is model 5190/5191 duplex Teleport system. It is composed of two full loaded 19″ racks with 48×12 (transmitter) and 12×48 (receiver) switch modules built using 12×12 sub-modules, signal monitoring panels, master-slave controller, fiber optics modules, power supply modules, signal attenuation control and L-band amplifiers across both transmitter and receiver racks.Download ourFull Integrated Solutionsor read further on ourCustom Applicationpage.

我们的最新设计基于模块化平台,可以使用16x6交换机的模块化构建块增加SATCOM系统的大小,以最大为94x110矩阵。该平台具有可拆卸的墨盒和18 dB的低噪声系数。系统的美是信号路由阶段(在输入阶段和输出之间易于互换,在无源扇出,风扇或横杆交换类型之间,或者可以使用这些类型的组合来制作混合动力切换矩阵。要了解更多,请联系我们技术支援bob官方下载地址团队与工程师交谈。
