TUNABLE NOTCH FILTERING IN MULTI-TRANSMIT APPLICATIONS |
摘要 |
<p>A radio frequency (RF) communication device comprises a first signal propagating circuit and a second signal propagating circuit, which together enables simultaneous transmission. The first signal propagating circuit is configured with a first tunable notch filter within a first transmit path and the second signal propagating circuit is configured with a second tunable notch filter within a second transmit path. A controller is communicatively coupled to a respective first tuning component and second tuning component of the tunable notch filters. The controller selectively tunes at least one of the tunable notch filters during signal propagation to produce a specific combined notch filtering response that reduces a level of IMD on at least one receive carrier frequency of at least one propagating signal. Aspects of the disclosure also provide a method for making the communication device.</p> |
