Description
M/A-COM's SW-262 is a hermetic SP4T switch that
features ultralow DC power consumption. SW-262 is
operates with a single +5V bias. Due to the use of GaAs
MMICs the switch features fast switching speed and high
intercept points. The switch is packaged in a metal flatpack,
and is available with screening upon request. This switch is
ideal for industrial and military applications where high
reliability is required.
