RF module and method for testing an RF module

A radio frequency (RF) module comprising:

• a signal input;
• a signal output;
• an auxiliary terminal;
• a power amplifier electrically connected between the signal input and the signal output;
• a first switch electrically connected between the power amplifier and the signal output;
• and
• an RF filter section electrically connected between the first switch and the signal output, wherein:
• the RF filter section has a first RF filter and a second RF filter electrically connected in parallel with the first RF filter;
• and
• the first switch has a signal input, two or more signal outputs, and an auxiliary connection, wherein:
• a first signal output of the two or more signal outputs is coupled to the first RF filter;
• a second signal output of the two or more signal outputs is coupled to the second RF filter;
• the auxiliary connection is coupled to the auxiliary terminal;
• and
• the first switch is configured such that, during an an analysis mode, the auxiliary connection is electrically connected to one of the two or more signal outputs.
