Adding a PA to RF IC Circuit

  1. Jan 12, 2010 #1
    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" [Broken]. 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?
