ABSTRACT:
A signal delay assembly for a high power linear amplifier, using feedforward circuitry to reduce distortion, comprises an interdigital delay line unit with included directional couplers. The structure of the interdigital delay line is substantially in a parallelepiped housing. A co-axial connector constructed as an integral part of the delay unit is used for signal connection to the amplifier.
