The performance analysis is conducted through simulation and measurement towards the 3GPP specifications. This Rf front end mobile transceiver provides the function of modulation and demodulation of the 3G cellular communications digital signal in the air link. It is implemented with a commercial standard dual conversion transmitter operating at 1920MHz to 1980MHz and a heterodyne receiver operating at 2110MHz to 2170MHz. The Transceiver consists of power amplifier (PA), variable gain power amplifier driver, low noise amplifier (LNA), autimatic gain control (AGC) amplifier, mixers (up conversion and down conversion), modulator, demodulator and frequency synthesizer (with oscillator and phase lock loop) as the main building blocks. All these modules are commercially available in the market. The main RF parameters of the transceiver such as adjacent channel leakege ratio (ACLR), occupied bandwidth, output power, noise figure (NF), gain , third order input intercept point (IIP3) and selectivity are simulated and measured against the stringent requirements in the 3GPP specifications. Agilent Advanced Design System (ADS) Version 1.5 with 3GPP Design Library is used as an initial simulation tool. Based on the simulation results, suitable modules are acquired and cascaded into a laboratory prototype. The performance of the prototype developed is analysed through a series of measurements. The transceiver was found to be compliant to the 3GPP standard. the transmitter has a measured maximum output power of +23.6dBm, EVM of 6.45 percent ( when Pin= -20dBm), ACLR ( at 5MHz offset) of approximately -37dBc and an occupied bandwidth of 4.159 MHz when operating at 1950MHz. The receiver achieve a NF of 6.71dB and IIP3 of -14.9dBm at maximum gain of 92dB in the baseband I and Q output and could detect a signal level as low as -117.3 dBm with a bit error rate (BER) of less than 10-3 when operating at 2140Mhz. This transceiver is powered from a 3 cells NiMH battery pack at 3.6V ( 700mA) 2002 Thesis http://shdl.mmu.edu.my/45/ http://vlib.mmu.edu.my/diglib/login/dlusr/login.php masters Multimedia University Research Library
