Dual - MOSMIC- two AGC Amplifiers for TV-Tuner Prestage
with Integrated Band Switch for One-Line Switching
Comments
MOSMIC - MOS Monolithic Integrated Circuit
Description
The Dual-MOSMIC TSDF12830YS, assembled in
the well-known SOT-363 plastic package, is a combi-
nation of two different MOSMIC amplifiers with com-
mon Source and common Gate 2 leads and an
integrated switch. One of the MOSMIC stages is opti-
mized for use in VHF applications, especially regard-
ing cross modulation performance and noise figure at
lower VHF frequencies, whereas the other stage is
optimized for use in UHF applications regarding gain
and noise figure performance at higher frequencies of
UHF range. The integrated switch is operated by the
Gate 1 bias of the UHF amplifier on Pin 6. All of the
Gates are protected against excessive input voltage
surges by integrated antiserial diodes between them-
selves and Source.
Features
Two differently optimized amplifiers in a
single package. One of them has a fully
internal self-biasing network on chip and
the other has a partly integrated bias for
easy Gate 1 switch-off with PNP switching transis-
tors inside PLL -IC
Internal switch for saving lines on PCB layout as
well as external components
Integrated gate protection diodes
Low noise figure, high gain
Typical forward transadmittance of 31 mS
resp. 28 mS
Superior cross modulation at gain reduction
High AGC-range with soft slope
Main AGC control range from 3 V to 0.5 V
Lead (Pb)-free component
Component in accordance to RoHS 2002/95/EC
and WEEE 2002/96/EC
Applications
Low noise gain controlled VHF and UHF input stages
with 5 V supply voltage, such as in digital and analog
TV tuners and in other multimedia and communica-
tions equipment.
