T7024 2.4GHz front-end doubt

t7024

Hi,

I am designing a zigbee application using the T7024 (PA+LNA) but I don't understood the switch driver application on page 10 (Figure 11) of the Design Guide:

http://www.atmel.com/dyn/resources/prod_documents/doc4549.pdf

The idea is to use the MC13224 or CC2530 transceiver and the T7024 to increase zigbee range.

Could someone please give an idea of how to implement the 1/4 wave circuit of the design guide?

Thanks,

Andre Fernandes

Use the following free program and calculate the length of the λ/4 (90 degrees) transmission line function the PCB you are using.

Thanks vfone.
That hepls a lot.

If we opt in use this IC I'll layout the microstrip with this program.
