This measurement was conducted using a single cell (1x ADAR1000, 4x ADTR1107) on the ADAR1000EVAL1Z board. All tests were conducted at 10 GHz RF Frequency. The Tx output was combined using a 4:1 combiner and feed into a ADL6010 envelope detector. The detector Vout was connected to the high impedance input of an oscilloscope. The oscilloscope trigger signal was the TR pin of the ADAR1000.
Pulse characteristics are a 1 kHz pulse repetition frequency with a 50 us pulse width (5% duty cycle).
