衛(wèi)星調(diào)諧器 DBS TUNER
The TA1322FN is a WidebAnd down-converter which can
operate at input frequency ranging from 850 MHz to 2200 MHz.
Intended primarily for use in satellite tuners, this IC includes an
oscillator, a mixer, an IF amplifier and a PLL.
A digital filter structure for WidebAnd filtering
is proposed. It consists of two allpass filters and a linearphase
FIR filter. One major advantage of this structure is
that the allpass filters are functions of zM which implies
that the maximal sample frequency is M times higher for
this structure than for the corresponding conventional
structures.
