    Abstract: Amplifiers with multiple outputs and separate gain control per output are disclosed. In an exemplary design, an apparatus (e.g., a wireless device or an integrated circuit) may include first (640) and second (660) amplifier circuits. The first amplifier circuit (640) may receive and amplify an input radio frequency, RF, signal (RFin) based on a first variable gain and provide a first amplified RF signal (RFampl). The second amplifier circuit (660) may receive and amplify the input RF signal (RFin) based on a second variable gain and provide a second amplified RF signal (RFamp2). The input RF signal may include a plurality of transmitted signals being received by the wireless device. The first variable gain may be adjustable independently of the second variable gain. Each variable gain may be set based on the received power level of at least one transmitted signal being received by the wireless device.

    Abstract: Techniques for routing and shielding signal lines to improve isolation between the signal lines are disclosed. In an exemplary design, an apparatus includes first, second, and third signal lines and a switch. The first, second, and third signal lines are configurable to carry first, second, and third signals, respectively. The switch is coupled between the second signal line and AC ground and is closed when the second signal line is not carrying the second signal. The second signal line isolates the first and third signal lines when the switch is closed. Adjacent signal lines are not active at the same time. A signal line may include positive and negative signal lines, which may have at least one cross over in order to cancel coupling between the positive and negative signal lines.
