What are High Frequency Transistors?

High Frequency (RF) Transistors are transistors that are used for small signals that run at high frequencies for high-speed switching applications.

These are transistors that are used for high frequency signals and must be able to switch on and off at very high speeds.

High frequency transistors are used in HF, VHF, UHF, CATV, and MATV amplifier and oscillator applications.

They have a maximum frequency rating of about 2000 MHz and maximum Ic currents from 10 to 600mA.

They are available in both npn and pnp forms.
