Embodiment Construction

[0024] This disclosure provides details and examples of techniques for wireless communication including frequency planning for digital power amplifiers. Figure 1A An example of a wireless communication device architecture is shown. The wireless communication device 100 may communicate with one or more other wireless communication devices using one or more antennas 140, 142 and one or more wireless communication technologies (eg, over a wireless network). Device 100 may be a system on a chip (SoC) including one or more integrated circuit (ID) devices. Device 100 may be a plurality of IC devices coupled to each other on a common circuit board. In some implementations, device 100 may be an electronic device, such as an access point (AP), base station (BS), wireless headset, access terminal (AT), client station, or mobile station (MS).

[0025] Wireless technologies used may include Near Field Communication (NFC), Bluetooth (BT), WiFi, and mobile telephony technologies such as ...

Abstract

Systems and techniques related to wireless communication devices and digital power amplifiers include, according to one aspect, a device that includes: a modulation circuit for a radio frequency transmitter having a local oscillator frequency; a digital power amplifier coupled to the modulation circuit; and a digital power an amplifier-coupled clock input; wherein the clock input provides a clock signal to the digital amplifier at a sampling clock frequency; and wherein the local oscillator frequency is an integer multiple of the sampling clock frequency.

Description

[0001] Cross References to Related Applications [0002] This disclosure claims the benefit of priority to US Provisional Application Serial No. 61 / 911,725, filed December 4, 2013, entitled "FREQUENCY PLANNING FORDIGITAL POWER AMPLIFIER," which is hereby incorporated by reference in its entirety. Background technique [0003] The present disclosure relates to wireless communication devices and circuits used therein. [0004] Wireless communication devices typically use power amplifiers to amplify signals prior to transmission over the air. The efficiency of power amplifiers often affects the performance of devices such as mobile phones or base stations. For mobile phones, higher efficiency power amplifiers can increase battery life. For base stations, higher efficiency power amplifiers reduce power consumption, which leads to lower operating costs. However, besides efficiency, production cost is also important. [0005] Digital Power Amplifier (DPA) technology is a promis...
