Dear Tim,
You can find reference design for CC1020 here: http://www.ti.com/tool/cc1020eb_refdes

Best Regards, R.M
Bit curious, why do you want to use the CC1020 and not any of the newer radios we have to offer?
Please check out the reference design ( www.ti.com/.../cc1020emx_refdes) For Tx only you can ground the RF_IN pin.
