Attenuator
Product Description
The RF2421 is a monolithic switched attenuator. The
device is built using a Gallium Arsenide process technol-

ogy and has a single step attenuation of 10dB. The input
0.018

and output of the device has a low VSWR 50Ω match.
The RF output can drive up to +16dBm. This unit is

by digital means. No negative supply voltages are
required, and the current consumption is less than 5µA
when the attenuator is off.
