A fishing pole support or harness for connecting a user to a fishing pole to support and control the fishing pole. The system comprises a sample processing unit and a container unit for receiving a supply container supplying the sample processing unit with a bulk liquidsolid andor a waste container receiving waste from the sample processing unit. The invention provides an RF-LDMOS transistor having an improved RF ruggedness, while not, or at least to a much lesser extent, compromising the RF performance of the RF-LDMOS transistor.
