The ADM-5974CH is a broadband, moisture resistant MMIC LO buffer amplifier. The ADM-5974 provides efficient, optimized LO drive to all Marki mixers in band with no required negative bias or sequencing. It is built with a moisture resistant pHEMT process to allow the bare chip to pass biased HAST testing without a hermetic seal. Second harmonic rejection can be tuned to very low levels using the optional negative bias. The ADM-5974 can also be used as a broadband signal amplifier. The bare die features enhanced moisture resistance for improved reliability.
