Description

To improve the flexibility of the individual satellite, TESAT has developed the new product line of Flexible Programmable Microwave Power Modules (FPMs). Building on this FPM concept in order to gain an attractive product for Tesat’s main customers the main task of the project “300W Ku-Band Single FPM” involved the development of a EPC/LCAMP assembly for higher power class FPM in the currently most frequently employed frequency band for telecommunication payloads, a 300W Ku-Band Single FPM. A subsequent qualification campaign to verify the performance needed in a space environment and conducted using an EQM EPC/LCAMP assembly with a representative 300W TWT concluded the project. The EPC built within the project showed the capability to handle more than 500W of DC power and the ability to adapt the RF output power of the TWT to an instantly in-orbit needed level in a range of 3 dB. A high-performance serial TM/TC interface (CAN) has proven its capability to control and observe the whole amplifier in operation. With this project Tesat has developed and qualified an improved product to complement the current spectrum of Tesat’s amplifier products.

Short Speaker Information

Jens Freese received the Dr.-Ing. degree from the Darmstadt University of Technology, Germany, in 2007. His research activities were linked to array antennas and beam forming algorithms. Afterwards he joined TESAT Spacecom GmbH, Backnang, Germany, as a microwave amplifier development engineer. In 2012 he became responsible for the microwave and power electronics advance development group in the amplifier products line. Since 2015 he is the head of the RF amplifier development department. In this position he is responsible for customer driven and advance development topics in the field of TWTAs and SSPAs for satellite communication payloads.
