El "Olympus Propagation Experiment (OPEX)". Aspectos del cabezal de R.F. de las estaciones receptoras
(1985)
Conference report
Open AccessThe design guidelines for a coherent receiver for the Olympus propagation experiment at 12.5, 20 and 30 GHz are discussed. The receiver channels can be locked to a main PLL in the 12.5 GHz channel, thus decreasing the loss ... -
Improvement of the pull in range and acquisition time of a microwave PLL system by injection locking the V.C.O
(1987)
Conference report
Open AccessThe requirements of large pull-in range and short acquisition time in microwave and millimeter wave phase locked oscillators are of great importance since the free running VCO frequency may be sorne tens of MHz off the ... -
Mezclador equilibrado a 30 GHz para la recepción de la baliza B2 del satélite Olympus
(Universidad Politécnica de Madrid (UPM), 1988)
Conference report
Open AccessThe design and performance of a 30-GHz mixer is presented. The mixer is to be used in the RF front end of an earth station for the OPEX experiment with the propagation beacons of the ESA's Olympus satellite. It uses a ... -
PLL's de microondas con el VCO sincronizado por inyección: aplicaciones
(1989)
Conference report
Open AccessA system which combines the properties of the PLL systems and the injection locking ones is described. Its theoretical behaviour is analysed and some practical applications are discussed. Its performance in these aplications ... -
