DUAL N-Channel MOSFET Tetrode
• Low noise gain controlled input stages of UHF-
and VHF-tuners with 5V supply voltage
• Two AGC amplifiers in one single package
• Integrated gate protection diodes
• Low noise figure
• High gain, high forward transadmittance
• Improved cross modulation at gain reduction
• High AGC-range
