Abstract
Circuits for wireless communication on multiple frequency bands are provided. In accordance with some embodiments, transceivers are provided, the transceivers comprising: a first quadrature hybrid having a first in port, a first iso port, a first cpl port, and a first thru port; an antenna coupled to the first in port; a first transmitter having an output coupled to the first cpl port; and a first receiver having an input coupled to the first cpl port.
Claims13
A transceiver comprising:
- a first quadrature hybrid having a first in port, a first iso port, a first cpl port, and a first thru port, wherein when a signal having a power is received at the first in port, a first half of the power of the signal is provided to the first cpl port as a first wave and a second half of the power of the signal is provided to the first thru port as a second wave, and wherein the first wave is shifted 90 degrees from the second wave;
- an antenna coupled to the first in port externally from the first quadrature hybrid;
- a first transmitter having an output coupled to the first cpl port externally from the first quadrature hybrid;
- a first receiver having an input coupled to the first cpl port externally from the first quadrature hybrid;
- a second transmitter having an output coupled to the first thru port externally from the first quadrature hybrid;
- and
- a second receiver having an input coupled to the first thru port externally from the first quadrature hybrid.
