Abstract: A method and apparatus for linearizing a baseband filter are provided. The apparatus is configured to, via a first conducting module, receive a first current signal. The apparatus is further configured to, via a converting module, receive a second current signal, generate a voltage signal based on the second current signal, and apply the voltage signal to the first conducting module. An amount of the second current signal received by the converting module is based on an amount of the first current signal flowing through the first conducting module. The apparatus is also configured to, via a second conducting module, control an output current signal based on the voltage signal. The output current signal is controlled to be a linear replica of the first current signal for in-band frequencies.

Abstract: One aspect of an apparatus for wireless communications is disclosed. The apparatus includes a controller, a first transceiver, and a second transceiver. The first transceiver is configurable by the controller to support first communications through a cellular network to at least one of a packet-based network and a circuit-switched network. The second transceiver configurable by the controller to operate with the first transceiver to support first communications through the cellular network in a first mode and support second communications through an access point to the packet-based network in a second mode. In an aspect, the second transceiver is further configured to switch from the first mode to the second mode by moving its wireless connection from the cellular network to the access point while maintaining a network-layer connection to the cellular network.
