Abstract

A radio frequency, RF, frontend (12) for a vector network analyzer, VNA, measurement system (10) is described. The RF frontend (12) comprises a first frontend portion (20) and a second frontend portion (22). The first frontend portion (20) comprises a first directional unit (28) being configured to couple an RF signal traveling towards at least one port (16) out of at least one measurement path (18). The first frontend portion (20) further comprises a second directional unit (34) being configured to couple an RF signal traveling away from the at least one port (16) out of the at least one measurement path (18). The second frontend portion (22) comprises a frequency combining unit (42) and a switching stage (40) having a first switching state and a second switching state such that the second frontend portion (22) provides two different functionalities associated with the two switching states. In the first switching state of the switching stage (40), a stimulus RF signal is coupled into the measurement path (18) by means of the frequency combining unit (42), which is used as a reference signal for performing measurements. In the second switching state of the switching stage (40), the RF signal traveling away from the at least one port (16) is coupled out of the measurement path (18) by means of the frequency combining unit (42).
