Novel cost-effective passive intermodulation measurement technique using a single power amplifier

•Standard PIM analyzers employ 2 PAs, making them expensive measurement instruments.•PA is a very expensive and its price is proportional to its operating frequency.•This research makes PIM measurement affordable by using single PA.•Presented system has a residual PIM of -104.5dBm.•PIM of any DUT from -60 to -94.5dBm @ 43dBm can measure using the presented analyzer.
