BF904AR
Key Features
- Specially designed for use at 5 V supply voltage
- Short channel transistor with high transfer admittance to input capacitance ratio
- Low noise gain controlled amplifier up to 1 GHz
- Superior cross-modulation performance during AGC. APPLICATIONS
- VHF and UHF applications with 3 to 7 V supply voltage such as television tuners and professional communications equipment. DESCRIPTION Enhancement type field-effect transistors. The transistors consist of an amplifier MOS-FET with source and substrate interconnected and an internal bias circuit to ensure good cross-modulation performance during AGC. The BF904A, BF904AR and BF904AWR are encapsulated in the SOT143B, SOT143R and SOT343R plastic packages respectively.
