摘要
采用LTCC工艺进行手机天线开关滤波器的设计,用于手机天线开关发射端GSM850/900MHz、GSM1800/1 900MHz。整个LTCC滤波器体积为2.5mm×3.2mm×0.75mm,其中包含两个低通滤波器,用于二次谐波和三次谐波的抑制。GSM850/900通带插损小于0.75dB,带内二次谐波抑制度大于23dBc,三次谐波抑制度大于40dBc;GSM1 800/1 900通带插损小于0.7dB,带内二次谐波抑制度大于26dBc,三次谐波抑制度大于28dBc。
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 re- spectively. 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.
