Ferrite Microwave Technologies (FMT) offers a wide array of high-power coupled water loads employ the cooling as the absorptive media. These directly coupled water load devices offer rugged, broad band design. Typically, cooling achieves by way of water or a water-glycol mixture. Ferrite also offers a comprehensive line of high-power coaxial water loads.
Types of Coupled Water Loads
Ferrite manufactures a few different types of coupled water loads. Two designs we’ll focus on here are the ceramic block window type and the teflon antenna type. See the information below to learn about two common types of water loads.
Ceramic Block Window Type
These units use a ceramic window to directly couple the RF energy into the cooling media. This type of design allows for the absorption of very high power levels while giving the user the added benefit of a smaller size when compared to refractory grade absorptive material.
Bandwidth is limited to 15% and a stable inlet coolant range must be met for stable performance. The maximum inlet coolant temperature is driving by the average power of the application. These designs can accommodate cooling mixtures of water, water/glycol. Pressurization required for high peak power applications. Note that for Vacuum use these units can be TiN PVD for mitigation of multipaction.
Teflon Antenna Type
These units use a PTFE Antenna in the water column to couple the RF into the cooling media. This type of design allows for the absorption of high power levels while giving the user the added benefit of a small size when compared to refractory grade absorptive material.
These units are typically larger than the Ceramic Block Window type. Bandwidth is limited to approximately 35% and a stable inlet coolant range must be met for stable performance. The maximum inlet coolant temperature is driving by the average power of the application. These designs can accommodate cooling mixtures of water, water/glycol. Pressurization required for peak power applications.
