BG3123

The BG3123 is a kind of dual N-Channel MOSFET tetrode. If you want to more about this IC, please go to our website for more information.

The features of BG3123 can be summarized as (1)two gain controlled input stages for UHF and VHF -tuners e.g. (NTSC, PAL); (2)optimized for UHF (amp. B) and VHF (amp. A); (3)integrated gate protection diodes; (4)high AGC-range, low noise figure, high gain; (5)improved cross modulation at gain reduction.

The absolute maximum ratings of BG3123 are (1)drain-source voltage VDS: 8 V; (2)continuous drain current amp. A/amp. B ID: 25/20mA; (3)gate 1/ gate 2-source current ±IG1/2SM: 1mA; (4)gate 1/ gate 2-source voltage ±VG1/G2S: 6V; (5)total power dissipation Ptot: 200 mW; (6)storage temperature Tstg: -55 to 150°C; (7)channel temperature Tch: 150°C.
