Revision of RFX2411N

[sathishvps]

Now I am in designing process of RFX2411N LNA with nRF51822 while I Search for a reference schematic it has two revision 1.2 and 2.0.Which will I use?

I gone through your layout,You provide only a nordic section.I need to clarify on the RFX2411N because of the schematic version problem.It has two version.So update me with RFX2411N LNA section

RFX2411 should be placed in the 50 Ohm reference point, after all the components in the reference layout.

It will be nRF51 + matching network for the chip - RFX2411 - antenna matching network.

If RFX2411 requires any specific components to work properly, they are included in "RFX2411" above.

ok thanks .RFX2411N Provide a different version of schematic with respect to 50ohm reference point because the two version have a different component value at the impedance point of nrf51822 .If it is possible update me a design with RFX2411N

Okay, I see. I would recommend you to contact Skyworks to find out which reference layout with RFX2411N you should use.
