Embodiment Construction

[0014] An amplifier including a power amplifier is used in a wireless terminal. For example, power amplifiers are used in cellular phones and smart phones in 2G / 3G / 4G / 5G cellular systems, WiFi devices, and most other wireless access technology radios. Power amplifiers are also used in many computing devices that incorporate wireless access technology, such as desktop computers, laptop computers, tablet computers, netbooks, and other types of computers. Many wireless access technologies include communication protocols that use multiple frequency bands.

[0015] In some exemplary embodiments, the wireless terminal may simultaneously transmit on multiple frequency bands according to the wireless protocol. Different power amplifiers can be associated with each frequency band. In some exemplary embodiments, when the bias voltage applied to the power amplifier and the supply voltage applied to the power amplifier are controlled, the power amplifier may operate with high power efficie...

Abstract

The invention relates to reconfigurable bias and supply drivers for radio frequency power amplifiers. In some example embodiments, there is provided an apparatus. The apparatus may include a direct current voltage source and / or an alternating current voltage source to track a power envelope of a radio frequency signal. The apparatus may further include first and second power amplifiers with bias voltage inputs and a supply voltage inputs, and a switch matrix. The first input may be coupled to the direct current voltage source, the second input may be coupled to the alternating current voltage source. The outputs may be coupled to the bias and supply inputs to the power amplifiers. The switch matrix may enable activation of the first power amplifier, the second power amplifier, both the first and second power amplifiers, or neither power amplifier.

Description

Technical field [0001] The subject described in this article relates to RF power amplifiers. Background technique [0002] Many modern computing and communication devices are mobile. These mobile terminals include various consumer products and industrial products, including mobile phones, handheld computing devices, laptop computers, printers, and so on. Wireless infrastructure systems such as cellular systems and other wireless access systems use a wide range of frequencies to accommodate the data throughput requirements of the many simultaneous users of the system. In order to utilize multiple frequencies supported by one or more wireless access networks, the mobile terminal can operate on multiple frequencies. The frequency range may be very wide, which may require multiple power amplifiers in the mobile terminal. Power-efficient wireless access electronics including power amplifiers may help extend the good battery life of mobile terminals. Summary of the invention [0003...
