Versatile analog detector usable for both wideband video detection

(to –35 dBm) and low level detection to –55 dBm (with offset correction

and video filtering or averaging) Design limits drive to the video amp

providing fast recovery from high level pulses.

Average power detection is obtained at power levels below approximately –13 dBm.

For best pulse recovery DC supply pins should be bypassed with 1-10 uF depending on

pulse width, duty cycle and video load.

Simple output offset voltage trimming (over temperature) can be implemented by “pulling”

the output (Rout=50 ohms) through a 100 K resistor and DAC/PROM supply.
