ABSTRACT:
A circuit coupling an antenna to a load uses an integrated circuit differial amplifier with emitter feedback, a buffer amplifier and various adjusting networks to achieve constant output impedance independent of input loading over a wide range of frequencies. The adjusting networks also allow precision gain matching and phase matching between units.
