APPLICATION NOTES
This unit is DC coupled and employs a RF choke at the input (DC short). If the application
calls for the input to sink current there will be approximately an additional 1 mV of output
offset voltage for each 3 mA of current. Sink current should be limited to 100 mA max to
avoid choke burnout.
For higher supply voltages, up to ±15 volts, the positive supply pin must include a series
current limiting resistor, Rs = (Vs – 5) / 0.01 (e.g., Vs = +15v, Rs = 1.0K
Ω)
.
Average power detection is obtained at power levels below approximately –13 dBm.
For best pulse response the supply pins should be bypassed with an additional
1.0 µF capacitor. The unit contains 0.01 µF internal capacitors.
