Frequently Asked Questions

Q: What is the difference between BF195 and BF194?
A: Both are RF/IF transistors, but BF195 is optimized for oscillator and mixer duties with slightly higher frequency performance, while BF194 is better suited for IF amplifier stages. They can often be substituted in hobbyist projects.

Q: Can the BF195 be used in VHF circuits?
A: Yes. The BF195 is designed for frequencies up to VHF (100+ MHz) with stable gain and low noise, making it suitable for amateur radio and vintage VHF receiver designs.
