<p>The present invention pertains to a feed forward amplifying circuit (1) comprising signal delay compensation equipment. The signal delay compensation equipment includes one or more variable signal delay elements (9a,9b). The variable signal delay element(s) includes a plurality of signal delay components (Dk) and switching circuitry (15a,15b;15.1a,15.1b) providing a possibility of introducing at least one signal delay components, selected from the plurality of signal delay components, into a signal delay path. A tuning of the timing compensation becomes easy with the variable signal delay element(s), thus making the feed forward amplifying circuit (1) more suited for production on an industrial scale.</p> |
