Abstract
A tunable diplexer includes a high band port, a low band port, an antenna port, a high pass filter, and a low pass filter. The high pass filter is coupled between the high band port and the antenna port, and is configured to pass signals within a high pass band between the high band port and the antenna port. The high pass filter includes a high band path stop band zero, which is configured to selectively attenuate signals within a high band path stop band. The low pass filter is coupled between the low band port and the antenna port, and is configured to pass signals within a low pass band between the low band port and the antenna port. The low pass filter includes a low band path stop band zero, which is configured to selectively attenuate signals within a low band path stop band.
