Abstract (en)
[origin: EP0565943A2] A guide-microstrip transition including a decoupling filter on the power supply is described. The transition is used in hermetic active microwave modules (SSPA) with high packing. It comprises a glass bead coupling a microstrip of a MIC to a probe functioning as an antenna in a resonant cavity communicating with a wave guide. The probe also comprises a cylindrical conductor with very small diameter and electrical length equal to one-fourth wave length at a frequency of 20GHz connected to the centre of the armature of a discoid capacitor acting as a short-circuit for the RF. A connector is also connected to the centre of said armature and to a battery. The connector and the cylindrical conductor are aligned on the same axis of the glass bead. There is also described a triple amplification module obtained by using said transitions. <IMAGE>
