CC2595: How to interface cc2595 amp with cc2500?

Part Number: CC2595
Other Parts Discussed in Thread: CC2500,

I am trying to use cc2595 front-end amplifier in order to boost cc2500 transmitting power performance. Considering the matching needed between the transceiver and the amplifier I couldn't find the documentation needed in order to evaluate my design. Can you help me with that? Is there any similar reference design in order to understand what should I do?

Thank you very much for your time!

The input impedance of the CC2595 is 50 ohms with a typical input return loss of 15 dB. I am not familiar with the details of the CC2500 but I think that you can simply cascade the devices to boost output power. That is certainly the intent of the CC2595 gain block. There are no reference designs with this combination, but you can cascade the individual EVMs if desired.
