Advantech Wireless Inc of Montreal, Canada (which manufactures satellite, RF equipment and microwave systems) has launched the second-generation Super Compact TT Series gallium nitride (GaN)-based 300W C-band solid-state power amplifier block up-converter (BUC SSPA/SSPB), which offers 60% RF linear power increase while reducing energy consumption by 30% and reducing weight and overall size by 45%. In terms of linear power, the 300W unit is the equivalent of a previous 500W SSPA and of a 750W traveling-wave tube (TWT) amplifier.
The new units are specifically designed for maritime application, where bandwidth demand has increased exponentially, and where the high temperature in the radome is always a challenge, notes the firm.
"The improved GaN reliability and low size allow perfect integration into the ship stabilized antennas, where size is extremely important for perfect balancing, and where heat generation has to be reduced to the minimum," says Cristi Damian, VP business development. "The second generation of the 300W C-band GaN-based systems continues the tradition of the previous 200W C-band GaN-based SSPAs from Advantech Wireless, already deployed and installed on thousands of ships in the sea," he adds.
