Ratings based on +25 °C. APPLICATION NOTES Average power detection is obtained at power levels below approximately -13dBm. RF input is AC coupled (DC block). DAS8121 contains a plastic packaged IC. DAS8121 provides maximum video performance with no output load capacitance. However, the detector is capable of driving capacitive loads up to 100 pF without oscillations. Load capacitance above that specified may produce pulse overshoot and ringing.
