Abstract
An integrated semi-parabolic antenna/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 electrically connected to the printed circuit board carrying the down converter electronics. The 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 connected to an RF filter located at the input end of the printed circuit board. The RF filter is surrounded by an input ground shield which covers the RF filter circuit. The shield is soldered to the top and bottom ground planes of the printed circuit board. At the opposite end of the printed circuit board are two output I.F. amplifiers whose outputs are serially connected together. A coax ground shield engages the opposite end of the first printed circuit board in a perpendicular orientation so as to position the opposite end of the printed circuit board within the hollow interior.
