Balancierte 38/76-Frequenzverdoppler-MMICs auf PHEMT-Basis in Koplanar-Schaltungstechnik
Abstract
Two 38/76 GHz push-push frequency doublers have been realized in a 0.15 mu m GaAs PHEMT technology. The circuits are based on different 180 deg power divider structures: a Lange coupler followed by a 90 deg transmission line, and a balun. The circuits achieve maximum conversion gains of -4 and -6 dB for 12 and 14 dBm input signals, respectively. The fundamental suppression is approximately 30 dBc in both cases. To our knowledge, these results represent the best performance reported up to date for W-band balanced doublers.
