Description

Переходное устройство с одпотактпого иа двухтактный усилительный каскад, осуществл емое но схеме, так называемой, автобалансной фазоннверсин, имеет два существенных недостатка. Во-нервых, отсутствует отрицательна  обратна  св зь но основному каскаду и ноэтому частотна  характеристика основного каскада, онредел ема  нараметралн ламны н входной емкостью последующего каскада, не корректируетс : во-вторых, в шнроконолосных усилител х на трехолектродиых лылшах с большим усилением соиротивленне св з1г нтуитпруетс  значт1тельной входной емкостью ннвертерной ламиы, в реззльтато чего на iibicobMix частотах возможна значнтольна  аспмметргг .A transitional device with a single-stroke push-pull amplifier cascade, implemented according to the scheme of the so-called autobalance fazonnversin, has two significant drawbacks. B-nerve, there is no negative feedback to the main cascade and therefore the frequency response of the main cascade, which is determined by the parameters of the input capacitance of the subsequent cascade, is not corrected: secondly, in three-wire spectral amplifiers with greater amplification, it is identical to its own reflections. Significant input capacitance of the converter lamia, as a result of which, at iibicobMix frequencies, the value of aspmittrg is possible.

В нредлагаомом нереходном устройстве оба указанных }1едостатка могут быть сведены к минимуму, ирнчем нрп иолнозг ciiMiieTiiJin: обеих ламп каскада вли ние входных емкостей этих ламн на симл:етрню выходных нанр женнй мо/кет быть нолностью комненснровано.In the predlagate non-retractable device, both of the above-mentioned shortcomings can be minimized, by means of the ciiMiieTiiJin: both lamps of the cascade, the influence of the input capacitances of these lamps on the symbol: the output output nanometers can be completely compensated.

Сущность нзобретенн  но си етс  элсктрнческнми схемам: на фпг. 1-3, где Г-источник входного наир жени , ,Ti-усилительна  ламна основного каскада, Л2-уснлнтельиа  ламиа ннпертерного каска ,да, R-сопротивление анодной нагрузки, С-исреходна  е: 1кость, R, Ro-сонротпвлени  в цеп х сеток последзчогцего 1;аскада, Г, т -Зчастк  птнх сонротнвленин.The essence is invented but it is similar to electric circuits: on phpg. 1-3, where the G is the input source source,, the Ti-amplifier lumina of the main cascade, L2-type lamine-perperum helmet, yes, R-resistance of the anode load, C-and-e: 1 t, R, Ro-sonarity in the circuits nets of the last; 1; ascade, G, t; - Spare parts of the sonrotnvlenin.

На схеме, изобра/кенно1г на фпг. 1, оди  конец источника входиого тганр жеин  Г ирисоедпн етс  не к земле (как это вынолн етс  в схеме автобалансной инверснн), а к точке сонротивленн  р, к которой присоединена сетка лампы Л2.On the diagram, image / kenno1g on phpg. 1, at one end of the source of the input module, the iris does not connect to the ground (as is the case in the autobalance inverse scheme), but to the coordinate point to which the grid of the lamp L2 is attached.

Due to the fact that the grids of lamis are fed with equal, eg, out-of-phase, / or catgne, both optics of current, i.e., equal input capacitances of the lamps,
