Introduction to transmitter functionality

Transmitter functions are implemented in an RF ASIC. The ASIC contains a BB frequency low pass filter, which is tunable according to the signal bandwidth of the system in use. In addition, the ASIC contains separate RF paths comprising a final frequency IQ modulator and VGA amplifiers. WCDMA transmitter functionality In the transmitter side, an analogue I Q modulated signal is received from digital baseband into an RF ASIC and fed through a low pass filter. After the filter the signal is fed to...
