S-Band Transmitter for NAROM Student Rocket

Abstract [en]

Norwegian Centre for Space-related Education (NAROM) performs education within subject areas related to space, such as space physics, atmosphere and space technology. This thesis describes the development of a transmitter to be used in NAROM ́s studentrocket. The requirements were that the transmitter should send with FM at 2279,5 MHz with an output of at least 750 milliwatt and with a speed of 512 kbit/s when NRZ coding is used.The transmitter that was designed and tested in this project used an IC that modulated the signal to FM and sent it out on a low frequency. Then the frequency was multiplied by a IC to the correct value, 2279,5 MHz. Experiments showed that the transmitter worked satisfying, but a problem occurred: The frequency multiplier sent out unwanted overtones and the output power was to low. A final theoretical design was made to solve these problems. The final design uses the same modulation components as the tested transmitter, but filters are added and the amplifiers are changed to be able to handle the filters and give out a higher power. The transmitter can be use for other application that need a transmitter with bit-rate of up to 600 kbit/s and frequency range of 2250-2300 MHz without change of filters. If the filters is change the frequency range will be 2250-2550 MHz.
