The ADM-5931CH is a broadband, power-efficient, moisture-resistant GaAs PHEMT distributed amplifier chip. The ADM-5931CH is designed to provide optimal LO drive for T3 mixers.  Typically, it provides 11 dB of gain and +18 dBm saturated output power while requiring only 85 mA of current.  T3 linearity is enhanced by ADM-5931’s extended high frequency gain and lower even harmonic generation when compared to other distributed amplifiers in our catalog. It can be biased with internal circuitry, or with an external bias network for lower voltage and single supply operation. Additional applications include amplification of clock signals and general-purpose driver requirements in electronic warfare and test and measurement. The enhanced moisture resistance process enables the bare chip to pass biased HAST testing without the use of a hermetically sealed package.
