Abstract
An apparatus is disclosed for bi-directional active phase shifting. In an example aspect, the apparatus includes a wireless transceiver. The wireless transceiver includes at least one transmit path and at least one receive path. The wireless transceiver also includes at least one active phase shifter disposed in both the transmit path and the receive path.
Claims30
An apparatus comprising:
- a wireless transceiver including:
- at least one transmit path;
- at least one receive path;
- and
- at least one active phase shifter disposed in both the transmit path and the receive path.
2 more elements
An apparatus comprising:
- a wireless transceiver including:
- at least one transmit path;
- at least one receive path;
- and
- active means for phase shifting signals propagating along the transmit path and the receive path at different times.
2 more elements
A method for bi-directional active phase shifting, the method comprising:
- accepting an input transmit signal at a shared node of an active phase shifter at a first time;
- generating, based on the input transmit signal, a phase-shifted transmit signal at a transmit node of the active phase shifter at the first time;
- accepting an input receive signal at a receive node of the active phase shifter at a second time;
- and
- generating, based on the input receive signal, a phase-shifted receive signal at the shared node of the active phase shifter at the second time.
2 more elements
An apparatus comprising:
- a wireless transceiver including:
- at least one power amplifier;
- at least one low-noise amplifier;
- and
- at least one active phase shifter coupled to the power amplifier and the low-noise amplifier.
