Due to the proceeding automation in industry, new low-cost sensor systems are gaining more importance for every sector. Measurands like strain, pressure or temperature have to be determined in many applications and at best remotely. For this purpose one approach are frequency measurement systems for resonant surface acoustic wave (SAW) sensors that can be interrogated wirelessly as well. Six-port based sensor systems are already much more cost-effective than others since high performance calculation units are not necessary. However in many industries every saving gives a system a further edge over others. Due to this, in the following publication a six-port for frequency measurement systems is proposed which is reduced in cost and size by only using one analog output channel.
