Description

The CHE1270-QAG is a detector that integrates a matched detector diode (Vdet) and a reference diode (Vref). It is designed for a wide range of applications where an accurate transmitted power control is required, typically commercial communication systems. The circuit is manufactured with a Schottky diode MMIC process, 1µm gate length, via holes through the substrate and air bridges. It is supplied in RoHS compliant SMD package.

The input and output reference planes are located at 2.65mm offset (input wise and output wise respectively) from this axis. Then, the given Sij parameters incorporate the land pattern of the evaluation motherboard recommended in paragraph "Evaluation mother board".

As the voltage detection is the difference between Vref and Vdet, the external resistor value should be identical on these two ports. For information, a variation of 3% leads around 1mV variation of detected voltage. Due to ESD protection circuits on RF input, an external capacitance might be requested to isolate the product from external voltage that could be present on the RF access. ESD protections are also implemented on Vdet and Vref accesses. The DC connection (on DC pad) does 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.
