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.
