Travelling Wave Tube (TWT) amplifiers uncover application in satellite applications to supply amplification of sign power at really high frequencies. They may be appropriate for offering high sign power amplification at microwave signal frequencies which can be quite higher. As a lot as they provide these advantages, the TWT amplifiers come with some negatives.
Satellites that use TWT amplifiers experience poor harmonic signatures, intermodulation and high noise floor. They also take a lot of time to warm up and stabilize. They are also left on often, making it a safety issue. These tubes are a major cause of electromagnetic interference.
Maintenance comes into focus when we compare SSPAs and TWTs. With TWT, tubes need to be replaced time and again and other maintenance costs also apply. This is eliminated when you use SSPAs. This new technology has also eliminated the use of high-voltage power supplies, which have been seen to be unreliable and very lethal. These have become obsolete and are not used in latest models.
SSPAs are safe when operated at total power in very reflective hundreds. TWTs regularly failed when operated at total power. The latest SSPAs have benefited significantly from improvements which have made them immune to vibration and shock generating them far more efficient than TWTs.
One feature that is unique for the SSPAs is the ability to use the feature of power standby. This ensures that the amplifier can be put on standby to reduce power consumption. TWTs use vacuum tubes and take very long to warm up and they typically operate on an always-on mode. This makes them to draw power at a full rate, increasing their power consumption. SSPAs can be muted and this will shut off the power amplifiers and drivers. This will take the power consumption to zero.
The use of the SSPAs in TWT replacement brings the ability of ultra-fast standby that brings new gives for saving power and lowering warmth. The amplifier can be muted in in between bursts. It is unimaginable to mute a TWT amplifier in amongst bursts especially in amongst a TDMA signal.
As when compared with enough time for warming up vacuum tubes observed in TWT amplifiers, SSPAs can be called up from the standby method and stabilized to standard operations inside an extremely short time. The amplifier might be preserved on an on condition until the final little bit is transmitted then shut down. This indicates the SSPA could be in standby method for 80% of the time. This saves a lot around the energy intake.
When not actively transmitting data, the SSPAs can be put in standby mode. This can be instantly reactivated when needed in service. The use of the SSPA in such a way makes them a greener solution due to its power saving solution. This mode of operation reduces the lifetime operating costs of the SSPAs and for large teleport installations in corporations, it reduces electrical consumption.
