JN-RM-2079 NXP Semiconductors QN9090 module development reference manual The QN9090-001-M10 and QN9090-001-M13 (OM15069) modules are built on a standard 4–layer printed circuit board (PCB) with the individual layers organized as shown in Fig 4. Fig 4. PCB stack-up Note: The NXP PCB layouts assume use of the layers defined above. If a different PCB stack-up is used, then NXP does not guarantee performance. -

(trace) that is used to convey the RF energy between the radio and the antenna. QN9090 has a single ended RF output with a 3-component matching network composed of a shunt capacitor, a series inductor then another shunt capacitor. In addition, a 0-ohm resistor has been placed between the RFIO port of the chip and the first shunt capacitor. -

GND path between C10/C12 and C19 4.9 Reference Oscillator The NXP QN9090 device contains the necessary on-chip components to build a 32-MHz reference oscillator with the addition of an external crystal resonator. There is no need to use external capacitors because the QN9090 includes a bank of switchable capacitors that can be tuned to adjust the load capacitance (C ) that needs to be seen by the XTAL. -

Page 17: Screening Can
QN9090 module development reference manual 4.13 Screening can The QN9090 doesn’t radiate high spurs and it is very robust to EMC interferers so there is in principle no need for a screening can (or shielding can). Nevertheless, a footprint for a can has been added on the NXP modules and NXP recommends adding this footprint to any PCB. -
