Abstract
(EN)
The invention proposes a radio wave emission block 102 intended to modify a satellite-based reception installation into a cheaper emission/reception installation. The emission block 102 comprises a first input/output terminal 150 and a second input/output terminal 152 electrically linked to the first input/output terminal 150 by way of a band rejection filter 153 which rejects the intermediate emission frequency band. The invention also pertains to a tranmission device comprising a reception block 101 coupled with the emission block 102.
(FR)
L'invention concerne un bloc d'émission (102) d'ondes radioélectriques permettant de modifier une installation de réception par satellite en vue de former une installation d'émission/réception meilleur marché. Le bloc d'émission (102) comprend une première borne d'entrée/sortie (150), et une deuxième borne d'entrée/sortie (152), liée électriquement à la première borne (150) au moyen d'un filtre à élimination de bande (153) qui élimine la bande de fréquence intermédiaire d'émission. L'invention concerne aussi un dispositif de transmission qui comprend un bloc de réception (101) couplé au bloc d'émission (102).
