Stationary - MOPLL & Silicon Tuner Overview Of The DVB-T Tuner

Stationary - MOPLL & Silicon Tuner TUA6034T Overview of the DVB-T Tuner The RF input signal is splitted by a simple high pass Filter combined with IF & CB(Citizen Band) traps. Instead of band switching with PIN Diodes a very simple triplexer circuit is used. With a high inductive coupling the Antenna impedance is transformed to the tuned input circuits. The pre-selected signal is then amplified by the high gain self biased MOSFET BF2030W. One BG3130 double-MOSFET CAN be used for both VHF bands. In the following tuned bandpass Filter stage, the channel is selected and unwanted signals like adjacent channels and image frequency are rejected . Tracking traps of prestages and capacitive image frequency compensations of band Filters reject especially image frequencies. The conversion to IF is done in the one chip tuner-PLL IC, TUA 6034. TUA6034 is a real 3 band Tuner IC which has all the active parts for the 3 mixers, 3 Oscillators an IF driver stage, the complete PLL functions including 4 PNP ports & 1 NPN port(ADC input) for the band switching, and a wideband AGC detector for internal Tuner AGC. Combined with the optimized loop Filter 4 programmable Charge Pump currents, the balanced crystal Oscillator and the voltage controlled Oscillators which have superb characteristics thanks to Infineon's B6HF technology , the Tuner CAN achieve distinguished phase noise performance suitable for all digital applications. The balanced IF output signal of the TUA6034 is designed to drive directly a SAW Filter in the following IF stage. By Infineon Technologies Corporation
