FREQUENCY DIVIDER CIRCUIT, AND ANTENNA SWITCH LAMINATED MODULE COMPOSITE COMPONENT |
| 摘要 |
<p>PROBLEM TO BE SOLVED: To provide an optimally downsized antenna switch laminated module composite component. SOLUTION: The frequency divider circuit divides a signal into 3 different frequencies f1, f2, f3 having relations of f1<f2<f3 and (f2-f1)<(f3-f2) and is characterized in that a 1st divider filter that divider the signal into a signal with the frequencies f1 and f2 and a signal with the frequency f3 is connected to an antenna and a 2nd divider filter that divides the signal into the frequencies f1 and f2 is connected to the 1st branching filter.</p> |
