Ratings based on +25 °C. 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 +7 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. Guaranteed Parameter Typical 0 to 50 °C -40 to +85 °C Input Power Range (Min.) -10 to +15 dBm* -5 to +15 dBm* -5 to +15 dBm* Power Flatness (Max.) ±0.5 dB ±0.75‡ dB ±0.75‡ dB Threshold Temperature Stability (Max.) ±0.25 dB ±0.5 dB ±0.5 dB Threshold Hysteresis (Max.) ±0.2 dB ±0.5 dB ±0.5 dB Pulse Response (Max.) 50^ µsec 100^ µsec 100^ µsec Logic: Pin > Pth 11 1 Output Voltage Hi @ 5mA source 4.4 Volts 3.5 Volts 3.5 Volts Output Voltage Lo @ 5mA sink 0.1 Volts 0.25 Volts 0.25 Volts Supply Current (Max.) 1.0 mA 2.0 mA 2.0 mA * Measured in a 50 Ohm system at Vs=+5.0 Vdc.
