A well-known balanced conversion module containing two diodes, a power transformer, a hetero / ph transformer and an output | transformer, is a diode (connected to the terminals of the secondary winding of the signal transformer (C) a, the primary winding of which is connected to the syshap source and with by shodex circuit, diode cathodes, sub-1 to the terminals of the primary winding of the output / short circuit arrester of the formatter, the secondary winding of which is connected to the heater and to the # 4M OBI wire of the circuit, the primary winding of the hetero-given transformer is connected to the Goethe source home oscillations and with an obzim wire of the circuit, and the leads of the secondary winding of the heterodyne transformer are connected to the points of the secondary windings of the signal and primary windings of the output three-dimensional transformers 1, p. 244. However, the actual reapization of such a module is complicated due to the need to use three transformers. , the module does not provide selectivity on the receiver channel.

However, the pulled-out module does not allow the channel to be easily selected.

In the inventive Sh1fok m1olos1 "1t balanced loure6razuyu module,; having two diodes, the common connection of which is connected to the hub, a quaddan bridge is introduced, the first output of the bridge is connected to the anode of the first diode, the second bridge output is connected to the cathode of the second diode, the first input of the bridge is connected to the signal input of the module, and the second input of the soy / bridge is taken into account with the heterodyne input of the module.

The quad / axle bridge could be made on the basis of laconic lithium transmission and isch loops based on 01 sections of compressed lines 2. P. 59-68. h, cip. 69 - 71.

Due to the introduction of a quadratic bridge and the described changes in the circuit, the combination cocktails of the primary frequency of the first and second diodes, arising from the crawler, are in-phase summed in the module load, and the combined-voltage components of the lrome | full-time frequencies arising from the scrap with the frequency of the mirror kshal, are antiphase summed in the front, thereby obstructing the phase phase of the mirror channel of the Lriema.

In FIG. The lintcil circuit diagram of the lapped1 wide-band balanced balancing irrigation module with a 1® bridge is presented.

The module contains a first diode 1 and volt (NKN4 / u4od 2), the connection point of which is turned to the hub 3, square (press the bridge 4, the first input of the bridge 4 is connected to the source of oscillation 5, and the second input of the brain 4 is connected to the source of oscillation 6). The conversion module works as follows.

Due to the property of the quadrature bridge to ensure mutual decoupling between the first and second inputs, the proposed device retains the property of prototksha along the mutual circuits drove -.

In the same way, the positive effect of the use model consists in the phase suppression of the drop canalization of reception. A positive effect is achieved by switching the quadrature bridge instead of the inverting transformer and changing the polarity of switching one of the diodes of the converting module.
