Abstract
Aspects of the disclosure include a die and corresponding radio-frequency module and wireless mobile device. Examples of the die include, integral to the die, a power amplifier controller, a low noise amplifier, and an antenna switch in communication with both the power amplifier controller and the low noise amplifier.
Claims22
A die comprising:
- a power amplifier controller;
- a low noise amplifier in a receive path;
- an antenna switch module (ASM) in the receive path and a transmit path and in communication with both the power amplifier controller and the low noise amplifier, the ASM being configured to switchably couple the low noise amplifier to each of a plurality of antennas;
- and
- a band select switch in the transmit path and in communication with the power amplifier controller, the band select switch being communicatively unconnected to the low noise amplifier and communicatively unconnected to the ASM, the power amplifier controller, the low noise amplifier, the ASM, and the band select switch being integral to the die.

A radio-frequency module comprising:
- a die having, integral to the die, a power amplifier controller, a low noise amplifier in a receive path, an antenna switch module (ASM) in the receive path and a transmit path and in communication with both the power amplifier controller and the low noise amplifier, the ASM being configured to switchably couple the low noise amplifier to each of a plurality of antennas, and a band select switch in the transmit path and in communication with the power amplifier controller, the band select switch being communicatively unconnected to the low noise amplifier and communicatively unconnected to the ASM;
- and
- a power amplifier configured to be in communication with the power amplifier controller and physically separated from the die.
A wireless mobile device comprising:
- a plurality of antennas;
- and
- a radio-frequency module that communicates with the plurality of antennas, the radio-frequency module having a die and a power amplifier that is in communication with, and physically separated from, the die, the die having
- a power amplifier controller, a low noise amplifier in a receive path, an antenna switch module (ASM) in the receive path and a transmit path, and a band select switch in the transmit path, the power amplifier controller, the low noise amplifier, the ASM, and the band select switch being integral to the die, the ASM being configured to switchably couple the low noise amplifier to each of the plurality of antennas and being in communication with both the power amplifier controller and the low noise amplifier, the band select switch being in communication with the power amplifier controller, the band select switch being communicatively unconnected to the low noise amplifier and communicatively unconnected to the ASM.
