工作状态 | 开关装置的状态 | 功能说明 | ||||
SE1 | SE1 | SE1 | SE1 | SE1 | ||
在第一频带f1发射 | 开 | 关 | 关 | 关 | 开 | 在低频区的第一频带f1的发射状态。用于f2的两个λ-1/4波长导体LS1、LS2共同构成一个用于f1的λ-1/4波长导体(因为f2约等于2×f1)。由于SE5形成对地线P的短路,使得天线接口A转为空载。 |
在第二频带f2发射 | 关 | 开 | 开 | 关 | 关 | 在高频区的第二频带f2的发射状态。在SE3和天线接口A之间的用于f2的λ-1/4波长导体LS1将S3对地线P的短路转为天线接口A的空载。 |
在第一频带f1接收 | 关 | 关 | 关 | 关 | 关 | 用于第一频带f1的接收器E1通过两个λ-1/4波长导体SL1、SL2以波形阻抗正确的方式与天线接口A连接。 |
在第二频带f2接收 | 关 | 关 | 关 | 开 | 开 | 用于第二频带f2的接收器E2通过1/4波长导体SL1以波形阻抗正确的方式与天线接口A连接。S5相对接地线P的短路,经用于f2的λ-1/4波长导体转为第二接收器接口E2的空载。 |

在第一频带f1发射 | 10mA | -15V | -15V | -15V | 10mA | 插入衰减0.5dB,谐波间隔71dB,IP3输出:50dBm |
在第二频带f2发射 | -15V | 10mA | 10mA | -15V | -15V | 插入衰减0.5dB,谐波间隔71dB |
在第一频带f1接收(GSM) | -15V | -15V | -15V | -15V | -15V | 插入衰减0.5dB,基本上无电耗!只有二极管D1-D5的反向电流。 |
在第二频带f2接收(PCN) | -15V | -15V | -15V | 2mA(D4、5D导通) | 开路 | 插入衰减0.67dB,微量电耗! |
