Wide band attenuation a the direction of the said frequency compensated damping of high-frequency signals of a frequency band

摘要

Wide band attenuation a direction (10) for frequency compensated or of high-frequency signals of a frequency band, wherein the damping line a the direction of a region of variable agc - signal attenuation potentials is supplied, withan input (12) and an output (19);a first pin - diode (d1) in series between the input (12) and the output (19) and a frequency-dependent slope is connected via the frequency band and, via the agc - region;a second (d2) and a third (d3) pin - diode which, on opposite terminals of the first pin - diode (d1) are connected;Means for the production of a ac ground; anda first inductance (l2a and l2b), which the cathode of the second pin - diode (d2) connects with the ac ground and a second inductor (l3a, l3b), which the anode of the third pin - diode (d3) connects with the ac ground;characterized by thethat the first and second inductance (l2a and l2b, l3a, l3b) are switched in such a manner that their signal streams flow in each case in opposite directions, and that, between them, a negative mutual coupling effect is produced.
