Typical Connections and Padout of the Hybrid Integrated Circuit
5-5336(F).r3
* OUT– is delayed approximately 25 ps with respect to OUT+ due to the longer microstrip line associated with OUT–. An extra delay should be
added to OUT+ before connecting to the next circuit.

Description
Amplifier input; connect to detector anode, current should enter this node.
RF bypassed connection for the cathode of the APD.
APD power supply connection.
Supply voltage; –5.2 Vdc nominal.
Ground (back of HIC is also ground).
Negative temperature coefficient thermistor for APD gain control.
Noninverted data output (produces high-level output for current entering IN+).
Inverted data output (produces low-level output for current entering IN+).
