Description
M/A-COM’s AT-119 is a GaAs MMIC voltage
variable absorptive attenuator in a low cost, SOT-25
five-lead, surface mount plastic package. M/A-COM
fabricates the AT-119 with a proven monolithic GaAs
0.5 micron gate process that features full chip
passivation for performance and reliability.
