	There are a number of ion linear accelerators using RF focusing. Radio Frequency Quadrupole (RFQ) is the most useful RF linac in low energy range. Using of RFQ for medium energies is impractical because of low energy gain rate. Therefore, proposed to combine Drift Tube Linac (DTL), keeping tolerable energy gain rate, and RFQ. Such linac consists of periodic sequence of a several number of drift tubes and RF quadrupole electrodes, located in the same IH resonator. Different variants of the structure will be considered. Beam dynamics simulation will be carried out through these variants. Main parameters of the linac will be determine. The RF model design, providing combination of DTL and RFQ, will be proposed.
