| High Dynamic Range Low Noise GaAs FET August 2006 - Rev 03-Aug-06 CFB0303 Features Low-Noise Figure from 0.8 to 2.0 GHz High Gain High Intercept Point Highly Stable Easily Matched to 50 70 mil Package PHEMT Material Applications Cellular Base Stations PCS Base Stations Industrial Data Networks Description Celeritek's CFB0303 is a high performance GaAs PHEMT with 600 m gate width and 0.25 m gate length. The low noise figure and high intercept point of this device makes it well suited for use as the low-noise amplifier of the base station receiver in PCS, Japanese PHS, AMPS, GSM and other communications systems. The CFB0303 is in an industry-standard 70 mil package. It is surface mountable and available in tape and reel.
