MOSMIC^® for TV-Tuner Prestage with 5 V Supply Voltage
Comments
MOSMIC - MOS Monolithic Integrated Circuit
Features
• Easy Gate 1 switch-off with PNP switching transis-
tors inside PLL
• High AGC-range with less steep slope
• Integrated gate protection diodes
• Low noise figure
• High gain, very high forward transadmittance
(40 mS typ.)
• Improved cross modulation at gain reduction
• SMD package
Applications
Low noise gain controlled input stages in UHF-and
VHF- tuner with 5 V supply voltage.
