About RF Transistors
RF transistors are designed to handle high-power radio frequency (RF) signals in devices such as stereo amplifiers, radio transmitters, and television monitors. Like other semiconductor devices, they are made of materials such as silicon (Si) or germanium (Ge) and doped with impurities to induce changes in electrical properties. There are several basic types of RF transistors. Bipolar RF transistors consist of an N-type or P-type layer sandwiched between two layers of the opposite type. Both NPN and PNP configurations are available. MOSFET RF transistors are metal-oxide field effect transistors (MOSFETs) with a channel made of either an N-type or P-type material. Heterojunction field effect transistors (HFETs) require a negative power supply and are used mainly for driver or power amplification applications. Pseudomorphic high electron mobility transistors (PHEMTs) are used mainly in wireless devices and satellite communication systems.
Selecting RF transistors requires an analysis of performance specifications. Power gain, a measure of power amplification, is the ratio of output power to input power. Noise figure, a measure of the amount of noise added during normal operation, is the ratio of the signal-to-noise ratio at the input and the signal-to-noise ratio at the output. Both power gain and noise figure are expressed in decibels (dB). Other performance specifications for RF transistors include output power, operating frequency, and operating temperature. Some RF transistors support a temperature range and feature mechanical and electrical specifications that are suitable for commercial or industrial applications. Other devices meet screening levels for military specifications (MIL-SPEC).
