PIN DESCRIPTION Pin Name Description Power Supply B3 VDD Positive Supply Voltage B1 GND Power Ground Digital Inputs C3 SD Schmitt-triggered Shutdown. The device is active for SD = LOW. For SD = HIGH, it is brought into a low-power shutdown mode. C2 BS Schmitt-triggered Band Select pin. When BS = HIGH, RFIN1 is selected, when BS = LOW, RFIN2 is selected. Analog Inputs A1 RFIN1 RF Input connected to the coupler output with optional attenuation to measure the Power C1 RFIN2 Amplifier (PA) / Antenna RF power levels. Both RF inputs of the device are internally terminated with a 50 Ω resistance. Feedback A2 FB Connected to inverting input of output amplifier. Enables user-configurable gain and bandwidth through external feedback network. Output A3 Out Amplifier output BLOCK DIAGRAMS Figure 2.
