6 FAQs about [Solid state power amplifier satellite]
How many satellite amplifiers are onboard a satellite?
The new analyses consider a total of 18,902 amplifiers (6428 TWTAs, 2158 SSPAs, and 10,316 unspecified amplifiers) onboard 565 communications satellites launched from 1982 to 2016. This new study contains the largest number of satellites and amplifiers to date and compares output power, redundancy, and bandwidth capabilities.
What is a radially combined amplifier?
Radially combined amplifiers have been used for many years but typical uses are for radar and other non-data link applications. They provide many advantages to high power tube amplifiers by allowing the use of Solid State Power Amplifiers (SSPA) at much higher power levels than a single unit can support.
What is a GaAs power amplifier?
Today, GaAs is widely used in SSPAs at lower frequencies in applications requiring low to moderate output power levels; however, heat can limit its power output. GaN power amplifiers are a relatively new technology still in development.
How much power does a SSPA generate?
The SSPA includes also satellite interfaces (e.g., internal power supply generation unit, telemetry and telecommand functionalities) and measured results show an output power larger than the targeted 230W, with a PAE greater than 40%.
What is a high-power GaN-based SSPA?
High-power, GaN-based SSPAs require the synchronous optimization of several different technologies such as high-power ferrite devices, low-loss custom waveguide fabrication, power combiners, power supply conditioning circuits and MMICs.
What is a 58 GHz SSPA?
V-Band (58 GHz) SSPA for space communications. While TWTAs have played and will continue to play an important role in microwave satellite communication, we need new technology as we push into mmW frequencies. Much like the tube technology of early electronics, the new trend is a shift toward solid-state electronics.
