BFR540 NPN Bipolar Transistor SOT-23
BFR540 is an NPN silicon epitaxial low-noise microwave transistor in SOT-23 surface‑mount package. It features high gain, wide bandwidth, and low noise, specially designed for UHF, VHF, CATV, and radar‑related high‑frequency low‑noise amplification systems.
Our Advantages
- Ultra-high frequency up to 9GHz for wideband RF applications
- Extremely low noise figure for high-sensitivity reception
- High power gain and wide dynamic range
- Standard SOT-23 package for easy mass assembly
- Low capacitance and low leakage for excellent RF performance
- Stable linearity and high reliability
- Wide temperature range for communication equipment
