Polyfet RF Devices manufactures High Power Mosfet RF Transistors. The technology base is Silicon Gate Vertical and Lateral DMOSFETs. We specialize in MOS devices and have been in production since 1985. Our products are well established in the industry and we have a long history supporting both military and commercial applications.
The LDMOS is a new series of transistors that was introduced in Summer of 1996. LDMOS technology offer high gain , efficiency and linearity for operations at frequencies of up to 1500 Mhz. Typical gain at 1000 MHz is 13 dB and 16 dB at 500 Mhz. RF Power of up to 100W at 1 GHz with gain of 11 dB can be expected. LDMOS transistors have the added advantage of not having BEO ( Beryllium Oxide) in its construction; thereby eliminating a need for this toxic material.
The F series of Vertical DMOS Product line has been in production since 1985. We recently introduce a higher performance S series of Vdmos transistors which have much lower Crss - feedback capacitance. The enhancements in performance are in Rf power gain and output and in improved efficiency.
The fact that we build our devices using a modular die concept, there is no reason to expect us obsolete any one of our products. We have transistors that work off 50V, 28V and 12.5V power supplies.
**********************************************************************************
The following "F1" 28V series are phased out. We do not supply these parts anymore. Please use the S1A series for replacments.
The F1000 series of products are 28V products. RF Pout Power ratings vary from 20 Watts to 200 Watts.
The F1200 series of transistors works off 12.5V power supplies.
The F1400 series of transistors works off 50V power supplies. Power ratings of up to 250 Watts is available.
The F2000 series of products are 1 Ghz , 28V products. RF Pout Power ratings vary from 2.5 Watts to 20 Watts. These transistors may be used to 1300 Mhz. These are good driver transistors especially for broadband applications.
These are 12.5V transistors with RF power out of up to 40W with 12 dB gain.
