Overview
DISCRETE SEMICONDUCTORS DATA SHEET BF904A; BF904AR; BF904AWR N-channel dual gate MOS-FETs Product specification Supersedes data of 1999 Feb 01 1999 May 14 Philips Semiconductors Product specification N-channel dual gate MOS-FETs 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.
