ABSTRACT:
A UHF amplifier device interfaces between an antenna and a signal receiver. A circuit board has first and second planar input and output transformers formed within first and second grounding planes on the circuit board. An amplifier is formed intermediate the first and second planar transformers for amplifying UHF signals received from the antenna. Each of the input and output planar transformers include a first rectilinear leg and a rectilinear helix disposed in the same plane.
