BF1202WR Datasheet PDF - NXP

N-channel dual-gate MOS-FETs VHF and UHF applications with 9 V supply voltage, such as television tuners and professional communications equipment. FEATURES Short channel transistor with high forward transfer admittance to input capacitance ratio Low noise gain controlled amplifier up to 1 GHz Internal self-biasing circuit to ensure good cross-modulation performance during AGC and good DC stabilization. APPLICATIONS VHF and UHF applications with 3V to9 V supply voltage, such as 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.
