DESCRIPTION
The MwT-6 is a GaAs MESFET is ideally suited to narrow-band applications such as cellular telephone, PCN, point-to-point communica-
tions links, and other wireless applications as the driver transistor for the output power amplifier. The third-order intercept performance of
the MwT-6 is excellent, typically 12 dB above the 1 dB compression point. The chip is produced using MwT’s reliable metal system and
devices from each wafer are screened to insure reliability. All chips are passivated using MwT’s patented “Diamond-Like Carbon” process
for increased durability, Designers can use MwT’s unique BIN selection feature to choose devices from narrow Idss ranges, insuring
consistent circuit operation.
