Extending ADF4193 Vtune range

Extending ADF4193 Vtune range. Austin Harney. ADF4193 standard application circuit. 1. ADF4193 Extend Vtune range by bypassing internal diff amp stage and implement this using external quad stage op-amp and variable CMR voltage (e.g. OP484). Gain of Diff amp = R2d/R1d
