Title: Accurately Measuring PAE for Power Amplifier Post by vikas on Sep 14th, 2005, 8:05am Hello All, I am trying to characterize Power amplifier. I need to measure the PAE of PA over the frequency band and Vs Power out. The problem i have is that I am doing measurements in Gated Mode(spectrum Analyzer) with a pulse of 1/8 duty cycle. And for a PAE i need to estimate the continuous mode current. To make it more complicated PA is not completely off when it's enable signal(connected to the pulse of1/8 duty cycle) is off during the part of cycle. So I need to account for this leakage current as well since ammeter reading is just an average of current in OFF and ON state. Any comments and suggestion are welcome. I think i haven't been able to explain my problem clearly so let me know if somebody need a bit more explaination. Thanks, --Vikas |
