1. An apparatus comprising:
- a first RF highpass with tunable notch filter coupled between a first main port and a first common port, such that the first RF highpass with tunable notch filter is configured to have a first highpass notch frequency, which is configured to be tunable;
a first RF lowpass with tunable notch filter coupled between a second main port and the first common port, such that the first RF lowpass with tunable notch filter is configured to have a first lowpass notch frequency, which is configured to be tunable, wherein;
the first RF highpass with tunable notch filter and the first RF lowpass with tunable notch filter form a first RF diplexer configured to receive a function configuration signal and having the first main port, the second main port, and the first common port, andthe first RF diplexer is further configured to receive a lowband RF transmit signal and a highband RF transmit signal to provide a lowband RF antenna transmit signal and a highband RF antenna transmit signal simultaneously at the first common port, such that the lowband RF antenna transmit signal and the highband RF antenna transmit signal are Transmit Uplink Carrier Aggregation signals; and
RF system control circuitry configured to adjust, enable, and disable circuits within the first RF diplexer in response to the function configuration signal.

Abstract
A first RF diplexer, which includes a first RF highpass with tunable notch filter and a first RF lowpass with tunable notch filter, is disclosed. The first RF diplexer has a first main port, a second main port, and a first common port. The first RF highpass with tunable notch filter is coupled between the first main port and the first common port. The first RF lowpass with tunable notch filter is coupled between the second main port and the first common port. The first RF highpass with tunable notch filter has a first highpass notch frequency, which is tunable. The first RF lowpass with tunable notch filter has a first lowpass notch frequency, which is tunable.
