we have made and are using RF modules based on the ADF7021 transceiver with it's internal Rx/Tx switch. So far we are very satisfied with its performance. But we would like to go one step further and build a module with an external Rx/Tx switch (ADG919). I know that there are parasitic capacitance and inductance dependent from a specific pcb layout but any way are there any pre calculated values for matching LC networks for 433MHz, 868MHz and 915Mhz frequencies for such design?
