AT-264
Digital Attenuator, 4 Bit, Single Control
30 dB, 0.5 - 2.0 GHz
Features
• Single Control CMOS logic for each bit
• Attenuation 2 dB steps to 30 dB
• Low DC Power Consumtion: 50 uW
• Low Cost Plastic TSSOP-16 Package
Description
The M/A-COM AT-264 is a 4 bit, 2 dB step GaAs MMIC
digital attenuator in a low cost TSSOP-16 surface mount plastic
package. The AT-264 is ideally suited for use where high
accuracy, very low power consumption and low intermodula-
tion products are required. Typical applications include radio,
cellular, wireless LANs, GPS equipment and other gain/level
control circuits.
The AT-264 is fabricated using a mature 1 micron GaAs
MESFET process. The process features full chip passivation
for increased performance and reliability.
