Abstract
Certain aspects are generally directed to an apparatus for wireless communication, implemented using a configurable phase shifter network. The configurable phase shifter network generally includes a first switch coupled to a common terminal of the phase shifter network, a first phase shifter coupled between a first terminal of the phase shifter network and the first switch, a second switch coupled in parallel with the first phase shifter, a third switch coupled to the common terminal, a fourth switch coupled to the first terminal, and a second phase shifter coupled between the fourth switch and the third switch.

A configurable phase shifter network, comprising:
- a first switch coupled to a common terminal of the configurable phase shifter network;
- a first phase shifter coupled between a first terminal of the configurable phase shifter network and the first switch;
- a second switch coupled in parallel with the first phase shifter;
- a third switch coupled to the common terminal;
- a fourth switch coupled to the first terminal;
- and
- a second phase shifter coupled between the fourth switch and the third switch.
An apparatus for wireless communication, comprising:
- at least one amplifier;
- a first filter circuit coupled to the at least one amplifier;
- a first switch coupled to an antenna;
- a first phase shifter coupled between the first filter circuit and the first switch;
- a second switch coupled in parallel with the first phase shifter;
- a third switch coupled to the antenna;
