Dual NPN wideband transistor BFM520
FEATURES
• Small size
• Temperature and hFE matched
• Low noise and high gain
• High gain at low current and low capacitance at low
voltage
• Gold metallization ensures excellent reliability.
APPLICATIONS
• Oscillator and buffer amplifiers
• Balanced amplifiers
• LNA/mixers.
DESCRIPTION
Dual transistor with two silicon NPN RF dies in a surface
mount 6-pin SOT363 (S-mini) package. The transistor is
primarily intended for wideband applications in the
GHz-range in the RF front end of analog and digital cellular
phones, cordless phones, radar detectors, pagers and
satellite TV-tuners.
