2 / 15 page 2010 Sep 16 2 NXP Semiconductors Product specification N-channel dual-gate PoLo MOS-FETs BF1202; BF1202R; BF1202WR FEATURES Short channel transistor with high forward transfer admittance to input capacitance ratio Low noise gain controlled amplifier Partly internal self-biasing circuit to ensure good cross-modulation performance during AGC and good DC stabilization. APPLICATIONS VHF and UHF applications with 3 to 9 V supply voltage, such as digital and analogue television tuners and professional communications equipment. DESCRIPTION Enhancement type N-channel field-effect transistor with source and substrate interconnected. Integrated diodes between gates and source protect against excessive input voltage surges. The BF1202, BF1202R and BF1202WR are encapsulated in the SOT143B, SOT143R and SOT343R plastic packages respectively.
