HEXFET vs MOSFET | difference between HEXFET and MOSFET
IXYS-RF offers N-Channel enhancement mode RF Power MOSFETs that are optimized for RF and high speed switching. What is an RF MOSFET? MOSFET stands for metal-oxide-semiconductor field-effect transistor. It is a field-oxide transistor with a MOS structure. Toshiba offers typical single-gate MOS devices with one Gate (G) terminal, and dual-gate MOS devices with two Gate (G) terminals. Junction” high voltage MOSFETs are notoriously poor in this regard and should be avoided for rf amplifier service. The class of operation is defined by the drain conduction angle; the portion of the operating frequency period when the drain is conducting. Class A operation is fully conducting, 360°. MOS field-effect RF power transistor. Being electrically identical to the standard SD2931 MOSFET, it is intended for use in 50 V dc large signal applications up to 230 MHz. The SD2931-10 is mechanical compatible to the SD2931 but offers in addition a better thermal capability (25% lower thermal resistance).
This page compares HEXFET vs MOSFET and mentions difference between HEXFET and MOSFET.
MOSFET
The full form of MOSFET is Metal Oxide Semiconductor Field Effect Transistor.Figure-1 depicts 600 Volt SJ-MOSFET structure and circuit symbol.

HEXFET
HEXFET is trademark of power MOSFET developed by International Rectifier.The HEXFET structure is shown in the figure-2. As shown silicon oxide layer between gate and source regionscan be punctured by exceeding its dielectric strength. The symbol is same as power MOSFET as shownin the figure-1. It is a voltage controlled power MOSFET device.
When voltage is being applied between Gate and Source terminals, E-field is setupwithin HEXFET device. This electric field inverts the channel from P to N such thatcurrent can flow from Drain to Source in un-interrupted sequence of N-type silicon.
FETs can be of two types viz. enhancement mode and depletion mode.Enhancement mode devices require gate voltage of same sign as drain voltage in order topass the current.Depletion mode devices are usually ON and are turned OFF by Gate voltage of samepolarity as drain voltage.

Following points differentiate HEXFET from MOSFET devices.
➨All HEXFET® devices are enhancement mode devices.
➨As mentioned HEXFET® is trademark of International Rectifier.
➨Gate to source voltage of most of the HEXFET devices arebetween 10 and 30 V.
➨Example: IRF540 is HEXFET device and IRL540 is MOSFET device.

High Power Rf Transistors
The Infineon MOSFETs include several sub-categories, depending on whether the biasing resistor network at the RF input port is fully integrated (full-biased), partly integrated (semi-biased) or not at all integrated (non-biased). Download fsc laptops & desktops driver. Mainstream TV tuners are either a semi-biased or an intelligent-switching concept, while FM radio tuners mainly use single non-biased or single full-biased MOSFETs.
