The typical application of AD8318 is as shown in the figure. The AD8318 is designed to measure the 8GHz RF power, so the insulativity of the IN+, IN- pins and functional unit circuits is very important. The positive power supply port UPSI and UPSO must be connected to the same voltage, the UPSI port supplies the bias voltage to the input circuit, the UPSO port supplies the bias voltage to the low-noise output driver of the UOUT port. There are some independent public places in the AD8318. The CMOP can be used as the public place of the output driver. All the public places need to connect with the low impedance PCB ground area.
