AMP 1 S12
Amplifier 2 Input. Incorporates an internal DC-blocking capacitor and is internally matched to 50Ω.
This input is designed to be connected to a bandpass filter.
Electrical Ground
External Smoothing Capacitor for Internal Supply Voltage or Can Be Used as the External DC Supply
Pin to Eliminate the Need for a Bias-T on Pin 5
Amplifier 2 Output. Incorporates an internal DC-blocking capacitor and is internally matched to 50Ω.
DC bias on this pin serves as the power supply through a bias-T.
Amplifier 1 Input. Requires external DC-blocking capacitor and matching components.
AMP 2 Gain Select. Open is high-gain mode. Short to ground is low-gain mode.
Amplifier 1 Output. Incorporates an internal DC-blocking capacitor and is internally matched to 50Ω.
This output is designed to drive a bandpass filter.
Ground. The exposed pad must be soldered to the circuit board for proper thermal and electrical
performance.
