VSWR DETECTOR FOR A TUNABLE FILTER STRUCTURE |
| 摘要 |
Embodiments of radio frequency (RF) filter front-end circuitry are disclosed that include a tunable RF filter structure having weakly coupled resonators and a Voltage Standing Wave Ratio (VSWR) control circuit. The VSWR control circuit is configured to detect a VSWR at a terminal of the tunable RF filter structure and to dynamically tune the tunable RF filter structure based on the VSWR. In this manner, the VSWR control circuit tunes the tunable RF filter structure to improve performance of tunable RF filter structure over variations in the VSWR. |
