The presented development was accomplished within a project sponsored by the BMBF (Federal Ministry of Education and Research) named COMPASS (Cardiac Output Monitor with Pulmonary Arterial SenSors / ref. no. 16SV3691). The project's aim is to develop an implantable system to measure the pressure together with the temperature in the pulmonary artery. This data makes it possible to calculate the cardio output, which makes a timely diagnose of an increasing myocardial failure for patients with a pre-existing illness possible. The implantable system consists of a sensor module integrated in a catheter that is led in the pulmonary artery. Further the sensor module is connected to an RF-capsule via the catheter, so that it allows a wireless data transfer to an extracorporeal receiving station. This contribution focuses on the sensor module's non-encapsulated components
