CGH31240

240-W, 2700 – 3100-MHz, 50-ohm Input/Output Matched GaN HEMT for S-Band Radar Systems

Cree’s CGH31240F is a gallium-nitride (GaN) high-electron-mobility transistor (HEMT) designed specifically with high-efficiency, high-gain and wide-bandwidth capabilities, which makes the CGH31240F ideal for 2.7 –3.1-GHz, S-band, radar-amplifier applications. The transistor is supplied in a ceramic/metal flange package.

Features:

  • 2.7 - 3.1 GHz Operation
  • 12 dB Power Gain
  • 60 % Power Added Efficiency
  • < 0.2 dB Pulsed Amplitude Droop

This Simulation of power amplifiers (PAs) for modern wireless base station and small cell systems is an essential part of the design process. At a cell site, the PA consumes the bulk of the dc power, generates the most heat, and thus represents the greatest operational cost. Maximum PA efficiency is a necessity to manage these costs, which is a sizeable challenge in a PA that also must be highly linear to support the complex multilevel modulation types and wide bandwidths used for current and developing wireless transmission standards. Accurate simulation allows
the PA designer to meet these challenges by exploring the available design options and then optimizing the circuit that is selected for the application.
