Patent EP-0432674-A3 (EP)
Title: Qam modulator with improved carrier suppression
IPC: H04L27/36
Filed: 1990-12-08
Abstract: A modulator suitable for 16 quadrature amplitude modulation (QAM) is designed as a double modulator (1), wherein a 16 QAM modulator (39) consists of two double modulators (1). One double modulator (1) has two partial modulators (1',1'') forming a bridge. Each partial modulator (1',1'') has two possible transmission paths: (6',6'') with a phase delay line (39',39'') which causes a 180 DEG  phase shift. On each of the two paths (6',6'', 7',7''), a semiconductor diode (D1',D1'',D2',D2'') is disposed in such a way that they provide the carrier (Uc) with a 180 DEG  phase inversion and are accordingly rendered conductive in unison, if no modulation voltage (Um) is applied, whereby the carrier is suppressed at the signal output (3'). When a modulation signal (Um) is applied, the balance is changed to push-pull, and one of the two paths (6',6'') assumes less impedance compared to the other path (7',7''), which leads to the generation of the modulated carrier voltage (Umc). Through its design as a double modulator (1) such that the transmission path is realized respectively via an electrically short path (7',7'') of one partial modulator (1',1'') and via a phase delay path (6'',6') of the other partial modulator (1',1'') or conversely, differences in the two paths are averaged. The double push-pull modulator (1) is used in radio link systems. The modulator (1) can also be used as a mixer.
