Abstract:
1. A transmitter module for a high-frequency stage of a wireless communication system having an input impedance Z i and an output impedance Z o , the system having a signal path embodied as transmission path with an input side and an output side, the signal path being disposed between a signal input and a signal output to be connected to an antenna, the transmitter module comprising: a carrier substrate having a top surface, metallization planes, dielectric layers between said metallization planes, and through contacts connecting ones of said metallization planes; a power amplifier being disposed on said top surface of said carrier substrate and in the signal path on the input side thereof, said power amplifier having an output impedance Z a low-pass filter disposed in the signal path at the output side, said low-pass filter having an input impedance Z an impedance converter carrying out an impedance transformation from Z at least one of said impedance converter and said low-pass filter having passive components at least partially embodied as at least one of:
