Abstract- Since 2015, Analog television disabled in Mongolia. So we have to fabricate own DVB-T2 television transmitter, receive antenna and settop box. We already have designed and fabricated own settop box by brand name “Must Sict Solution” . Now our settop box has been trading in market. Next project describes a general design technique for micro strip band pass filter, amplifier, exciter, modulator, antenna etc. There are used to convey DVB-T2 television signals. Now we are studying band pass filter design. The parasitic problems of DVB-T2 UHF band can be adjusted through impedance ratio K, which can enhance the performance of harmonic suppression. Compared to other filter types, this design shows probable results with excellent harmonic suppression performance.
