DESCRIPTION
The MwT-1 is a GaAs MESFET device whose nominal quarter-micron gate length and 630 micron gate width make it ideally suited to
applications requiring high-gain in the 100 MHz to 12 GHz frequency range. The straight geometry of the MwT-1 makes it equally
effective for either wideband (e.g. 2 to 6 GHz) or narrow-band applications. 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.
