The BFP460 is a low noise device that is part of Infineon’s established fourth generation
RF bipolar transistor family. Its transition frequency fT of 22 GHz, low current and
high robustness characteristics make the device suitable for amplifiers. It remains cost
competitive without compromising on ease of use.

This transistor provides high gain (16.67 dB@315 MHz) using Infineon Designer

Target application:
- Remote Keyless Entry (RKE) Application
