| Abstract: | The paper provides a new designed structure for LTCC low pass filter.Two low pass filters are used for transmitter channel in an antenna switch module.Their whole size is only 2.5 mm×3.2 mm×0.75 mm with good performance.The insertion loss of the GSM850/900 MHz LPF is only 0.75 dB,the second and third harmonic suppression is 23 dBc and 40 dBc respectively.The insertion loss of the GSM1 800/1 900 MHz LPF is less than 0.7 dB,the second and third harmonic suppression is 26 dBc and 28 dBc respectively. |
