Typical Applications
• Power Control in Communication Systems • Commercial and Consumer Systems
• CMOS Compatible Programmable
• Portable Battery-Powered Equipment
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
and output of the device has a low VSWR 50match.
The RF output can drive up to +16dBm. This unit is
intended for use in systems that require RF power control
by digital means. No negative supply voltages are
required, and the current consumption is less than 5µA
when the attenuator is off.
