The design of an S-band transmitter is described in detail in this paper and testing results are analyzed. The software simulates body structure and the frequency ranges from the resonance point.In order to realize the miniature, MEMS filter, microwave monolithic integrated circuit and micropackage thin film technics are adopted in the design. The test results show that the flatness of the gain of the S-band transmitter is less than 1 dB, the rejection of spurious signals in of the band is more than 80 dBc,the rejection of local oscillator is more than 57 dBc，and the suppresion of the third-order intermodulation is more than 66 dBc. The dimension of the whole channel is 55 mm×35 mm×14 mm,which has perfect performances and high integration. |
