ZL1CVD:
This is the block diagram for RX/TX if you need it..

Hi,ZL1CVD,
Many thanks for your kindly help!
The part have 4 signal port in the middle and the common filter just have two. That is what I am confusing. Or transformer or coupler?
It seems R/S did not provide the full detail schematics of RXTX pcb. Am I right?
Best Regards,
Ice-Tea:
Aside from the block diagram, I never found schematics.
ZL1CVD:
I haven't see schematics either.
There is 3 of those in the RXTX module. They could be a diplexer which would have at least 3 ports. Some filter used in cellular look like they have multiple ports but really only have 2 with lots of grounding points. I think its they way they etch the ceramic.

Hi,ZL1CVD and Ice-Tea,
Thank you!
The part already have 4 GND port at the corner and 4 signal port in the middle.
From the layout, it seems 2 port pass the 842mhz signal and the other pass the 1.2-2.2g signal. It is interesting to learn about the function of it.
Best Regards,
