CHPA0618-1-G45 Ultra-broadband spatially combined power amplifier
The CAP Wireless CHPA0618-1-G45 ultra-broadband power amplifier incorporates gallium
arsenide (GaAs) monolithic microwave integrated circuit (MMIC) technology into its revolutionary, patented (#7215220) Spatiumâ„¢ broadband spatial combining technology to achieve outstanding solid state power levels across an extended 6-18 GHz frequency range. This compact, affordable, reliable, solid state alternative to traveling wave tube amplifiers (TWTAs) is uniquely positioned to meet the demanding specifications of applications such as electronic counter measures (ECM), laboratory instrumentation, and electromagnetic compatibility/elec-tromagnetic interference (EMC/EMI) test, as well as narrower band applications like radar, microwave imaging, and satellite communications. The multiple element architecture provides protection from single point failures and facilitates even, dispersive, three-dimensional (3D) heat dissipation.
