Abstract
A converter for a satellite antenna including a housing (20) accommodating a circuit support (13, 24) and having a hollow waveguide (26) and an RF output (28), both of which can be connected to the circuit support. The manufacturing effort can be reduced in that, together with adapted metallic components (11, 12), the circuit support constitutes a self-contained, fully operable core module (10, 21) which can be built into the housing.
Claims16
A converter for a satellite antenna, said converter comprising a housing including:
- a) a first waveguide portion for coupling to the antenna;
- b) a first RF signal connection means for electrical connection to RF signal receiving means;
- and
- c) means for removably securing in said housing a self-contained replaceable core module, said core module comprising:
- (1) a base plate having an opening defining a waveguide passage positioned and dimensioned for close coupling to the first waveguide portion;
- (2) a cavity plate having a cavity positioned and dimensioned for close coupling to the waveguide passage;
- (3) a second RF signal connection means for electrical connection to the first RF signal connections means, and
- (4) converter circuit means disposed on a circuit support secured between the base plate and the cavity plate for converting a microwave signal received in the base plate waveguide passage to an RF signal produced at the second RF signal connection means.
