2.25 Volt Voltage Variable Absorptive Attenuator
42 dB, 1.8 - 2.5 GHz
Features
• Single Positive Voltage Control: 0 to +2.25 Volts
• 42 dB Typical Attenuation Range at 2.4 GHz
• Low DC Power Consumption
• SOT-25 Plastic Package
• Tape and Reel Packaging Available
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.
Applications
The AT-119 is ideally suited for applications that
require fine tuning, linear attenuation with voltage,
and very low power consumption.
Typical
automatic gain control circuits in satellite radio
receivers and other wireless receivers.
