Therefore the incident power detection versus incident power is identical to the reflective power detection versus reflected power. The reflective power detection versus incident power depends on both the coupler directivity and the reflective environment of the package. The following typical measured performances are obtained for a packaged detector, assembled on a connectorized board.

SMD mounting procedure The SMD leadless package has been designed for high volume surface mount PCB assembly process. The dimensions and footprint required for the PCB (motherboard) are given in the drawings above. For the mounting process standard techniques involving solder paste and a suitable reflow process can be used. For further details, see application note AN0017.

Best accuracy is obtained when: Vdetect_ I= Vref_R- Vdet_I Vdetect_R= Vref_I- Vdet_R As the voltage detection is the difference between Vref_X and Vdet_X (X= I or R), the external resistor value should be identical on these ports. For information, a variation of 2% leads around 1mV variation of detected voltage. ESD protections are implemented on Vdet_I, Vref_I, Vdet_R and Vref_R accesses. The DC connections (DC_R & DC_I) do not include any decoupling capacitor in package, therefore it is mandatory to provide a good external DC decoupling on the PC board, as close as possible to the package.
