Uhf Band Tv Transmitter Rf Front-end

The paper design to achieve a television transmitter RF front-end, the base signal will be mix to RF signal, the RF signal will be enlarge before export. Based on the actual needs identified the base signal will be mixed twice and enlarged twice before export. The local oscillator uses the PLL chip ADF4360-7 and ADF4360-8 which is from Analog Device. The mixer used Minicircuit Company's mixer. We choose Eudyna Company's GaAs FET flulOxm to design power amplifier, use Ansoft Company's simulation software to design.Transmitter is an important component of wireless communication system, this transmitter RF front-end research has a broad meaning. On different frequencies, transmitters for different areas, the basic principles are the same.
