DESCRIPTION

The FHX35LG is a High Electron Mobility Transistor(HEMT) intended for general purpose, low noise and high gain amplifiers in the 2-18GHz frequency range. This device is packaged in cost effective, low parasitic, hermetically sealed(LG) or epoxy-sealed(LP) metal-ceramic packages for high volume telecommunication, DBS, TVRO, VSAT or other low noise applications. Eudyna stringent Quality Assurance Program assures the highest reliability and consistent performance. ABSOLUTE MAXIMUM RATING (Ambient Temperature Ta=25°C)

Item Drain-Source Voltage Gate-Source Voltage Total Power Dissipation Storage Temperature Channel Temperature

*Note: Mounted on Al2O3 board (30 x 30 x 0.65mm) Eudyna recommends the following conditions for the reliable operation of GaAs FETs: 1. The drain-source operating voltage (VDS) should not exceed 3 volts. 2. The forward and reverse gate currents should not exceed 0.2 and -0.075 mA respectively with gate resistance of 4000. 3. The operating channel temperature (Tch) should not exceed 80°C.
