Abstract

A feed-forward amplifier having delay lines formed as microstrip transmission lines, for reliability and low losses, and signal amplifiers that have phase linearity, to match the delay lines, and a relatively high gain. The resulting device can be manufactured more reliably at relatively low cost, but has improved error cancellation performance, improved temperature stability, and is simple to tune after assembly, without removal of components.
