Bias Resistor Setting Input. Connect a resistor from this pin to ground.
AGC Loop Threshold-Level Input/Attenuator Control
Functional Control Bit (see Table 1)
Power-Supply Input. Bypass to ground with a 10nF capacitor as close as possible to the pin.
Attenuator Input (50I). Requires a DC-blocking capacitor.

Error Amplifier Input Voltage from an External Detector
Ground
Alarm Logic Output
Alarm Threshold Voltage Input. See the Alarm Operation section for operation details.
Functional Control Bit (see Table 1)
RF Output (50I). See the Typical Application Circuit for connection details.
Driver Amplifier Supply Voltage Input. Bypass to ground with a 10nF capacitor as close as
possible to the pin.
Exposed Pad. Internally connected to ground. Connect to GND for proper RF performance and
enhanced thermal dissipation.
