Abstract
The present disclosure describes an access point that filters the input to power amplifiers of a front end module. The access point includes a transmitter, a bandpass filter, a non-linear power amplifier, and an antenna. The transmitter produces an electrical signal. The bandpass filter filters the electrical signal from the transmitter to produce a filtered signal. The non-linear power amplifier amplifies the filtered signal from the bandpass filter to produce an amplified signal. The antenna transmits a first wireless signal based on the amplified signal.
Claims20
An access point comprising:
- a transmitter arranged to produce an electrical signal;
- a bandpass filter arranged to filter the electrical signal from the transmitter to produce a filtered signal;
- a non-linear power amplifier arranged to amplify the filtered signal from the bandpass filter to produce an amplified signal;
- and
- an antenna arranged to transmit a first wireless signal based on the amplified signal.
A method comprising:
- producing, by a transmitter, an electrical signal;
- filtering, by a bandpass filter, the electrical signal from the transmitter to produce a filtered signal;
- amplifying, by a non-linear power amplifier, the filtered signal from the bandpass filter to produce an amplified signal;
- and
- transmitting, by an antenna, a first wireless signal based on the amplified signal.
An access point comprising:
- an integrated circuit arranged to produce an electrical signal;
- and
- a front end module comprising:
- a bandpass filter arranged to filter the electrical signal from the integrated circuit to produce a filtered signal;
- a non-linear power amplifier arranged to amplify the filtered signal from the bandpass filter to produce an amplified signal;
- and
- an antenna arranged to transmit a first wireless signal based on the amplified signal.
