We manufacture our products in a World Class Wafer Facility. Advanced techniques of dry etching and mask steppers are used to improve uniformity of the transistor from production batch to production batch. Sub-micron process technology is used to achieve high performance. The transistors are manufactured by ion implant diffusion techniques.

Polyfet continues to make product improvements in both her Vdmos, Ldmos and GaN transistor lines. The higher input impedance of the Vdmos makes input matching simpler, especially for broadband frequencies. The lower gain of the Vdmos facilitates simpler stabilizing circuitry at lower frequencies. The low parasitic capacitances of the Ldmos makes it suitable for high frequency operations at high efficiencies. GaN affords very high input and output impedances, faciliting extrememly simple matching networks for broadband. GaN transistors have high RF power out to output capactianceratio; thus very high efficiencies can be acheived.

Important Notice
We have renamed our Ldmos transistors with a New Product Numbering System. You can look up a cross reference and learn about this improved product I.D. system.
