Advantech Wireless of Montreal, Canada (which manufactures satellite, RF equipment and microwave systems) has launched a 2.5kW TROPO C-band modular gallium nitride (GaN)-based solid-state power amplifier (SSPA).

The new Model ARMA-CL2500A operates over the low C-band Tropo frequency of 4.4–5.0GHz, and it is fully modular with built-in redundancy for all critical RF and power supply modules.

The new modular SSPAs are designed to be used as a direct replacement for older-generation Klystrons or traveling-wave tube (TWT) amplifiers. The most vital feature is its modular design, which allows plug in modules, as power supplies and RF modules can be hot-swapped without any interruption of service or noticeable reduction in power.

“Our TROPO line of GaN SSPAs is a perfect match for the new generation of high-data-rate, long-haul, cost-efficient communication links using tropo scattering technologies,” says Cristi Damian, VP business development. “This proves to be a viable solution when satellite links are either cost prohibitive or simply not available,” he adds.
