BF998WR
BF998WR is N-channel dual-gate MOS-FET manufactured by NXP Semiconductors.
FEATURES - High forward transfer admittance - Short channel transistor with high forward transfer admittance to input capacitance ratio - Low noise gain controlled amplifier up to 1 GHz. APPLICATIONS - VHF and UHF applications with 12 V supply voltage, such as television tuners and professional munications equipment. DESCRIPTION Depletion type field-effect transistor in a plastic microminiature SOT343R package with source and substrate interconnected. The transistor is protected against excessive input voltage surges by integrated back-to-back diodes between gates and source. CAUTION The device is supplied in an antistatic package. The gate-source input must be protected against static discharge during transport or handling. Marking code: MB.
