Abstract
Embodiments may relate to a radio frequency (RF) front-end module (FEM) with a first filter and a second filter. The RF FEM may include a termination inductor coupled to ground, and a switch that is to selectively couple the first filter and the second filter to the termination inductor. Other embodiments may be described or claimed.
Claims10
A radio frequency (RF) front-end module (FEM) comprising:
- a first filter that is to process RF signals in a first frequency range;
- a first plurality of resonators in series between an input matching network and an output matching network of the first filter;
- a second filter that is to process RF signals in a second frequency range;
- a termination inductor coupled to ground;
- a switch that is to selectively couple the first filter and the second filter to the termination inductor;
- and
- a shunt resonator in a ground path of the first filter, wherein the shunt resonator is communicatively positioned between a resonator of the first plurality of resonators and the switch.
