Problems solved by technology

However, if the radio design cannot be effectively converted to a digital design to reduce the size of the radio design, the integration of the radio circuit, which includes the digital transmitter part and the digital receiver part, will greatly increase the production cost
For example, in more advanced semiconductor processes, it is not cost-effective to design the transmitter part and the receiver part on the same wafer

Embodiment Construction

[0013] Certain terms are used throughout the specification and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open-ended term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that the first device is coupled to the second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

Abstract

One communication system includes a first die, a second die and a front-end circuit. The first die has an up-converter and a digital baseband (DBB) processing circuit. The second die is separated from the first die and has a down-converter. The front-end circuit couples an antenna to the first and second dies. The invention provides the communication system is capable of making the device smaller, cheaper, and have less current consumption through proper system partition and integration, such as different functional modules are implemented in different dies, thereby using the advantage of the transmitter digitization.

Description

technical field [0001] The present invention relates to transmitting and receiving wireless communication signals, and more particularly, to a communication system having an upconverter and a downconverter. Background technique [0002] Due to the advancement of deep sub-micro (deep sub-micro) complementary metal-oxide-semiconductor (CMOS) technology, digital circuits have become smaller and lower power consumption. That is, process scaling of the process allows more transistors to be implemented in the same area, or requires a smaller area to implement the same number of transistors. Therefore, in order to reduce the size and extend the battery life of portable devices such as mobile phones, various circuits need to be implemented through deep submicron CMOS processes. On the radio design side, there is a strong need to convert radio frequency (RF) / analog-intensive radio parts into more digital-intensive designs to take full advantage of the process' scalability.
