Broadband ring modulator for very short electromagnetic waves - has four-diode bridge coupled to specified line sections and filters

摘要

The first diagonal of the four-diode bridge (Q) in the ring modulation is connected to two transmission lines (12) leading to a shared low-pass filter (TP) whose output is the wanted signal mix (MS). The input signal is applied to the first end of the first diagonal via an input line (1). The converting signal (US) is applied via a second input line (10) to the first end of the second diagonal and via a second transmission line (11) to the second end of the second diagonal. Both diagonals have LC filters (L1, C1) to decouple the two inputs at the signal mix output frequency.
