Abstract
A dual band MDS/MMDS down converter receiving system wherein the support boom of a semi-parabolic antenna contains the down converter electronics. Located at the focal area of the semi-parabolic antenna are a pair of driven feed elements which are connected to the printed circuit board carrying the dual band down converter electronics. The dual band down converter is formed in an elongated shape to fit entirely within the formed hollow interior of the support boom. The down converter comprises a first printed circuit board which contains a low noise amplifier, two RF filters, and two diplexer filters located at the input end of the printed circuit board. The RF filters are mounted on opposite sides of the printed circuit board. The input is directly connected to the pair of driven feed elements. The RF filters are surrounded by input ground shields.
