Dow-Key® Microwave has been a prominent supplier in the SATCOM (satellite communication) industry for decades with a wide range of relays and switching solutions available for many different ground base and Teleport applications. The best in the RF switch industry, Dow-Key’s® engineering team is dedicated to support customers from product selection, custom design to RF switch system integration, and post product support.
Coaxial Switches: SPDT and Transfer DPDT and Multiposition switches
For wideband signals up to 40 GHz and for applications such as switching between two antenna signals using SPDT switches (401 and 402-series) or for routing two incoming signals to two outgoing paths using Transfer DPDT switches (411 and 412-series), our routing multiple signals to one output (SP3T-SP14T switches), Dow-Key® provides RF switch solutions with many choices. Selections such as connector types, control signals, indicators, RF terminations, ruggedized or non-ruggedized environments, RF power level, and many more options are available to meet all types of requirements.学到更多
许多SATCOM应用需要更复杂的开关模块，以支持发射器（扇出）和接收器（扇入）侧的低功率和高密度信号路由。bob官方下载地址处理许多I / O信号时，切换的复杂性迅速增加。Dow-Key's®Matrix产品系列提供软件控制的固态交换解决方案，用于路由输入以输出信号在典型的频带上输出信号：HF，IF，VHF，L，S和宽带。还提供了6×6至16x16的大多数常见配置，还提供了更高密度32x32,64x64或更大。Dow-key还可以提供10毫秒的快速系统级切换时间的解决方案，如果需要。

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.

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.
