WEAKLY COUPLED TUNABLE RF TRANSMITTER ARCHITECTURE |
| 摘要 |
RF communications circuitry, which includes a first tunable RF filter and an RF power amplifier (PA), is disclosed. The first tunable RF filter includes a pair of weakly coupled resonators, and receives and filters a first upstream RF signal to provide a first filtered RF signal. The RF PA is coupled to the first tunable RF filter, and receives and amplifies an RF input signal to provide an RF output signal. |
