TMS3705 component values to use when using different coil inductance

the range of the coil to use with the TMS3705 is ~440uH to ~700uH. in our reference we use a 440uH coil 

 (see page 15)

i would not recommend going up to such a heavy coil value for the reader side. that inductance value is more like what is needed on transponder side.

if you need to use less windings (like something you can make on PCB reasonably) i am also attaching a design that was done to translate the TMS3705 antenna requirement from this high inductance to 47uH and makes it single ended. the FET IC might be obsolete, i'm sure someone makes a replacement for it.

its simple. for sure you can resonate the higher inductance coil (2.8mH) with 500pF, but then this issue would be that any cabling you add to it would be adding to the capacitor value that you added for resonance. so it becomes a problem immediately. if you use lower inductance and larger cap, then the parasitic capacitance the cabling adds has less of an effect on the tuning. 

i did a study on that, using HF, which is also magnetic field. since this circuit is resonant at similar impedance, i think its relevant to mention - i found no difference whatsoever between # of turns and read range, keeping constant the power out, Q factor and tag size(s). Now in my case i was dealing with 1 to 4 or 5 turn coils which were in the high nH to 3uH range, so narrow range and tiny difference in the R component of the inductor in comparison to your proposal, where you have much larger inductor, where the R value difference will be higher and lower the Q, which results in a lower coil current versus using the reference value (range) of inductance. this should lead to a reduced read range.
