Adding a Power Amplifier to an RF IC Circuit

[RDReavis]

Hello all,

I'm trying to design a circuit that utilizes the http://www.analog.com/en/rfif-components/short-range-transceivers/adf7020/products/product.html" . What I'm worried about is getting everything to match properly; the PA requires a 50 ohm input, and after dropping it into the circuit, the combined impedance seen at the Tx/Rx node will change, throwing off both Tx and Rx.

Any suggestions as to where I might begin?

Thanks,
Richard D. Reavis

You really need to have good simulation tools and test equipment to work with RF IC/PCBA design. What tools do you have available? What SPICE package and libraries do you have at your disposal? Do you have any PCBA EM simulation software?
