Voltage Variable Absorptive Attenuator
30 dB, 0.5-2.0 GHz
Features
• Single Positive Voltage Control: 0 to +5 Volts
• 30 dB Voltage Variable Attenuation
• ± 2 dB Linearity from BSL
• Low DC Power Consumption
• Temperature Range: -40°C to +85°C
• SOIC-8 Plastic Package
• Tape and Reel Packaging Available
• Fast Switching Speed
Description
M/A-COM’s AT-110 is a GaAs MMIC voltage
variable absorptive attenuator in a low-cost SOIC 8-
lead surface mount plastic package. The AT-110 has
a faster switching speed than the AT-108 or AT-109.
The AT-110 is ideally suited for use where linear
attenuation
consumption are required.
Typical applications include radio, cellular, GPS
equipment and automatic gain/level control circuits.
The AT-110 is fabricated with a monolithic GaAs
MMIC using a mature 1-micron process. The
process features full chip passivation for increased
performance and reliability.
Note: Reference Application Note M513 for reel size
information.
