Advantech Wireless releases second-generation GaN-based 1250W Ku-band SSPA/SSPB for satellite broadcast teleports

Advantech Wireless Inc of Montreal, Canada (which manufactures satellite, RF equipment and microwave systems) has launched the second-generation gallium nitride (GaN)-based 1250W Ku-band SapphireBlu UltraLinear SSPA/SSPB (solid-state power amplifier/solid-state power block) for satellite broadcast teleports.

The second-generation SapphireBlu Class of UltraLinear GaN-based SSPAs and block up-converters (BUCs) is suitable for high-power, wide-frequency band uplinks. One single GaN-based SSPA offers higher performance in multi-carrier mode than several linearized traveling wave tubes (TWTs) and Klystrons, making them suitable for large teleports and broadcast industry. The new systems can saturate all transponders of an entire satellite and obtain maximum bandwidth/power efficiency.

"These units are designed as an alternative to legacy TWTs and Klystrons in large teleports," says VP business development Cristi Damian. "By removing the need for expensive indoor filter-combining schemes, UPS [uninterruptible power system], air conditioning systems, and expensive outdoor waveguide runs, a single 1250W Ku-band second-generation GaN unit can easily replace 10 or more Klystrons or indoor TWTs," he adds. "In many cases, this allows consolidation of traffic from multiple antennas and multiple satellites to a single antenna and a single satellite," Damian continues. "These teleport architecture changes will then result in massive OpEx cost reductions, and will free up the cash for the teleport operator. The initial cost of investment is recovered in most of the cases in just one year of electricity bill savings."

The new UltraLinear GaN-based SSPAs and BUCs are redundant-ready, with power expandable to 3kW by phase combining; high power density in a compact, rugged, weatherproof package with considerable reduction in size, weight, and energy consumption.
