Communication transmitters structures and solving.
1. Generating of RF signals: Theorethical basis of ostsillators. Stabilization of frequency, parametrical and quartz stabilization. Frequency synthesizers.
2. Amplification of RF signals: Classification of amplifiers. Basic of amplifiers design. Matching and loading stages. Circuit design of amplifiers. Rising of output power in amplifiers. Bridge stages. UHF amplifiers. Linearization of RF power amplifiers.
3. Modulation of RF signals: Amplitude modulation, Angle modulation. SSB modulation. Separating of wireless channels (FDMA, FDD, TDMA, CDMA). Representation of digital signals. Digital modulation (PAM, ASK, FSK, MSK, BPSK, QPSK, 16-PSK, QAM). Bit rate error (BER) and effectivity of broadband channel. |
