R TH =100 Ohm to 100 KOhm unless otherwise specified. ^ R TH = 1 KOhm. † Pin ≤–15 dBm. ‡ 50% RF to 10 or 90% Video Response time for input change ≥3 dB above Pth. DTS4001 This unit is DC coupled and employs a RF choke at the input (DC short). DO NOT bypass the Threshold Control pin. Capacitance greater than 50pF may cause instabilities. Keep the threshold programming resistor or circuit close to this pin. Average power detection is obtained at power levels below approximately –13 dBm. The output of this unit is derived from an op-amp, not a true logic device. Connect external threshold resistor from Rcntl port to ground.
