Overview
DISCRETE SEMICONDUCTORS DATA SHEET BF1201; BF1201R; BF1201WR N-channel dual-gate PoLo MOS-FETs Product specification Supersedes data of 1999 Dec 01 2000 Mar 29 Philips Semiconductors Product specification N-channel dual-gate PoLo MOS-FETs 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.
