MCL´s MT3400 and MT4400 outdoor travelling-wave tube amplifiers (TWTAs) are reliable, rugged and economical solutions for satellite uplink applications. The devices have now been made more energy efficient: the MT3400 is available with a 400 W linear TWT, drawing 1100 W as opposed to 1500 W, while the MT4400 offers a 750 W linear TWT, drawing 2000 W versus 2400 W.
These new TWT options are only offered in Ku-band at this time. Both of these state-of-the-art amplifiers are available for C-, X-, Ku- and DBS-band applications and include such features as rugged construction for extreme environments, software communications configuration for both remote and computer interfaces, continuous attenuator adjustment shown in dB, auto power control and status.
The TWTAs can also be customised to include options such as an internal L-band block up-converter, an internal lineariser, Ethernet interface, option at 60°C, or a handheld or remote controller. Redundancy can be achieved through 1:1, 1:2 or phase combined systems.
