Product Details

AF180 Germanium PNP Transistor - Classic UHF Front-End Amplifier

The AF180 is a shielded PNP germanium transistor, purpose-built for UHF reception and mixing in vintage TV and radio receivers. Its four-lead design with integral shield minimizes interference, making it the go-to choice for restoring or building retro RF front-end circuits that demand low noise and reliable gain.

Functions & Applications

Shielded 4-Lead Design: Integral shield prevents RF interference and crosstalk in sensitive front-end stages.
Germanium Technology: Naturally low noise floor ideal for weak-signal UHF reception.
UHF Optimized: Purpose-built for VHF/UHF mixer and amplifier stages in classic TV/radio receivers.
Vintage-Compatible: Drop-in replacement for original AF180 units in retro equipment restoration projects.

Frequently Asked Questions

Q: Is the AF180 suitable for modern breadboard circuits?
A: The AF180 is primarily a vintage part designed for UHF TV receivers. While it can be breadboarded, it is best suited for restoration work or specialized RF applications requiring its low-noise germanium characteristics.

Q: What is the complementary NPN germanium transistor for RF work?
A: For similar RF front-end performance, consider the AF179 (NPN germanium) or equivalent NPN germanium transistors from the same era.

Notes

Vintage germanium part; NOS stock. Genuine low-noise performance for RF front-end stages; not recommended for general-purpose switching applications.
