Abstract
A system and method adapts to interfaces utilized in a radio frequency transceiver. The system and method be utilized by an amplifier. The amplifier can include an input stage configurable to one of a plurality of external interfaces. The external interfaces can include a DC feed external interface or a DC decoupling external interface. The amplifier can include an amplification circuit configured to receive a signal at the input stage and amplify the signal. The external interfaces can be associated with a front end module.
Claims20
An apparatus for radio communication, comprising:
- an amplifier input stage selectively configurable to a plurality of external interfaces, the external interfaces comprising a DC feed external interface and a DC decoupling external interface;
- and
- an amplification circuit configured to receive a signal at the amplifier input stage and amplify the signal.
A method of processing an RF signal, the method comprising:
- receiving a radio frequency signal from a first band of a front end module at a first configurable amplifier input stage, wherein the first configurable amplifier input stage is selectively configurable to a plurality of external interfaces;
- selectively configuring the first configurable amplifier input stage between at least a DC feed external interface and a DC decoupling external interface signal;
- and
- amplifying the radio frequency signal from the first band.
A system, comprising:
- a front end module having a filter or duplexer circuit;
- a direct current (DC) decoupled interface;
- a DC feed path interface;
- and
- a low noise amplifier (LNA) comprising an adaptable input stage for selectively receiving from the DC decoupled interface and the DC feed path interface, wherein the DC decoupled interface and the DC feed path interface are external to the LNA.
