FHX35LG Super Low Noise HEMT FEATURES
• Low Noise Figure: 1.2B (Typ.)@f=12GHz • High Associated Gain: 10.0dB (Typ.)@f=12GHz • Lg ≤ 0.25µm, Wg = 280µm • Gold Gate Metallization for High Reliability • Cost Effective Ceramic Microstrip (SMT) Package • Tape and Reel Packaging Available
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’s stringent Quality Assurance Program assures the highest reliability and consistent performance.

*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 4000Ω. 3. The operating channel temperature (Tch) should not exceed 80°C.
