A radio frequency front end system with an antenna system including a first antenna. A transmit and receive system includes at least a first transmit and receive module having a transmit unit transmits a first radio frequency transmission signal to the at least one first antenna. A receive unit receives a first radio frequency reception signal from the at least one first antenna. A parasitic signal removal unit removes a second radio frequency reception signal received at the at least one first antenna and back-injected into the transmit unit of the first transmit and receive module.
A radio frequency front end system, comprising:
The radio frequency front end system of claim 10 wherein the first phase conversion unit is formed by a first input terminal of a first 90° hybrid coupler connected to an output of the first transmit amplifier unit, a second input terminal thereof connected to an output of the second transmit amplifier unit, a first 0° output terminal thereof connected to the second output terminal, and a second 90° output terminal thereof connected to the first output terminal.
The radio frequency front end system of claim 13 wherein the first transmit amplifier unit and the second transmit amplifier form a Doherty power amplifier.
A radio frequency front end system, comprising:
The radio frequency front end system of claim 19 wherein the first transmit and receive module includes a resistor connected between the second output terminal of the transmit unit of the first module and ground.
The radio frequency front end system of claim 19 wherein the first transmit and receive module further includes a transmit/receive switch having a first, second and third switch terminal, the first switch terminal being connected to the at least one first antenna, the second switch terminal being connected to the first output terminal of the transmit unit, and the third switch terminal being connected to the receive unit of the first transmit and receive module.
The radio frequency front end system of claim 19 wherein the receive unit includes an receive path, the receive path including a receive amplifier.
The radio frequency front end system of claim 19 wherein the first and second transmit amplifier are power amplifiers form a Doherty power amplifier.
The radio frequency front end system of claim 19 wherein the antenna system includes a phased array antenna.
A balanced amplifier architecture for a phased array MmWave transmitter, comprising:
