MwT-15
26 GHz Power
GaAs FET
DESCRIPTION
The MwT-15 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 500 MHz to 26 GHz frequency range with power outputs ranging from 100-200 milli-watts. The
straight geometry of the MwT-15 makes it equally effective for either wideband (e.g. 6 to 18 GHz) or narrow-band applications. The chip is
produced using MwT’s reliable metal system and all devices 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.
