Description & ApplicationsDual N-channel dual gate MOSFET General description The BF1208C is a combination of two dual gate MOS-FET amplifiers with shared source and gate 2 leads and an integrated switch. The integrated switch is operated by the gate 1 bias of amplifier b. The source and substrate are interconnected. Internal bias circuits enable DC stabilization and a very good cross-modulation performance during AGC. Integrated diodes between the gates and source protect against excessive input voltage surges. The transistor has a SOT363 micro-miniature plastic package. Features and benefits Two low noise gain controlled amplifiers in a single package; one with a fully integrated bias and one with a partly integrated bias Internal switch to save external components Superior cross-modulation performance during AGC High forward transfer admittance High forward transfer admittance to input capacitance ratio. Applications Gain controlled low noise amplifiers for VHF and UHF applications with 5 V supply voltage digital and analog television tuners professional communication equipment.
