Those aren't the only characteristic impedances available, however
two 50 ohm cables in parallel will accomplish it, with the proviso
they are identical in length.  The center leads at both ends are
paralleled; similarly the sheaths.  I have no idea why your circuit
would require semi-rigid cable except you must be careful to avoid
any sharp kinks and it would be a good idea to use coax with a
high percentage of sheath coverage.
