Both products offer very low insertion loss, which preserves the systems efficiency and averts the need for active cooling, enabling an optimal tradeoff between system performance, complexity and cost of ownership.

AT5g8Comb500

Due to physical limitations of the semiconductors power devices, at MW frequencies, a single power amplifier (or generator) can deliver limited CW power levels - up to few hundreds watts. The solid state RF energy systems can provide higher power levels by using multiple power amplifiers or generators, which outputs shall be combined with high performance power combiners.

The combiners shall satisfy multiple performance requirements:

• minimal insertion loss
• high power handling capability
• minimal amplitude and phase mismatch between the channels
• sufficient isolation between the RF inputs
• good input/output match

AndivaTech's proprietary, air-strip-line based design features best-in-class parameters in all required performance characteristics.
