Abstract:

For millimeter wave applications, MMIC is the best contemporary technology. Considering the requirements of the commercial and military applications on amplitude and phase linearity, it is necessary to reduce the nonlinearity of the amplifiers. There are several linearization techniques that are used to reduce the nonlinearity effects. In the context of the thesis, a special analog predistortion technique that is called &ldquo<br>self cancellation scheme&rdquo<br>is used to linearize a 35GHz MMIC amplifier. The amplifier to be linearized is used in the design of the predistorter, that is why i

Abstract:

In this thesis the design of a MMIC vector modulator operating in 9GHz-10GHz band is investigated and performed. Sub-sections of the vector modulator are 4-port (4.8dB) 1200 phase shift relative to the dedicated port power splitter, digitally controlled variable gain amplifier and the in phase power combiner. Alternative methods are searched in order to implement the structure properly in the given frequency band. The final design is appropriate for MMIC structure. 4-port (4.8dB) 1200 phase shift relative to the dedicated port power splitter is studied. The performance is simulated and optim

Abstract:

With the growth of smart phones, the demand for more broadband, data centric technologies are being driven higher. As mobile operators worldwide plan and deploy 4th generation (4G) networks such as LTE to support the relentless growth in mobile data demand, the need for strategically positioned pico-sized cellular base stations known as ‘pico-cells’ are gaining traction. In addition to having to design a transceiver in a much compact footprint, pico-cells must still face the technical challenges presented by the new 4G systems, such as reduced power consumptions and linear amplification of the

The first part describes the analysis and design of a Ka-Band power amplifier applied to the automotive collision avoidance radar system. In order to acquire the adequate linearity and efficiency of the system requirements, the architecture with two stages is adopted to design the power amplifier. The first stage utilizes class-A type to supply sufficient power gain. The second stage improves RF-to-DC signal ratio by class-AB type. By this way, the linearity of this circuit can also be improved. The semiconductor mate

碩士<br>國立成功大學<br>電機工程學系<br>89<br>This thesis presents design, implementation, and extensive measurement of a 5.7 GHz two-stage HBT MMIC power amplifier (PA) and 5.7GHz UNII (Unlicensed National Information Infrastructure) band transmitter and receiver RF front-end modules for IEEE 802.11a WLAN application. The design goal of the PA is to have 20dB gain and 20dBm 1-dB compression point at 3.6V DC bias. The measurement is performed on a FR-4 test fixture. The post simulation, including the effects of test fixture and bond-wire, agrees well with measurement. For the 5.7 GHz RF modules, RF is fro

Part 1 introduced the procedure for designing the RF transceiver module in an IS-95 CDMA system using link budget analysis. Part 2 was focused on a CDMA power amplifier integrated circuit design for Personal Communication Service (PCS) applications. The design procedure was introduced in detail and implemented in MMIC for using GaAs HBT foundry provided by the GCS Ltd.. The designed linear gain, output 1dB compression point and power added efficiency (PAE) are above 30 dB, 27 dBm and 36.7% respectively under a

Abstract:

State-of-the-art RF front-end circuits are typically designed to operate at a single frequency. With an increasing number of available wireless standards, personal mobile communication devices require an increasing number of individually designed RF circuits. To save space and cost, one alternative possibility is to reuse much of the circuitry by utilizing electronically reconfigurable topologies. The ubiquitous low-noise amplifier is one of the many circuits that can be redesigned with the reconfigurable aspect in mind. In this thesis, previous work in reconfigurable LNAs is reviewed as w
