Overview

RF2421 9 Typical Applications • Power Control in Communication Systems • CMOS Compatible Programmable Attenuator • Commercial and Consumer Systems • Portable Battery-Powered Equipment 10dB SWITCHED ATTENUATOR Product Description -A- The RF2421 is a monolithic switched attenuator.
The device is built using a Gallium Arsenide process technology and has a single step attenuation of 10dB.
The input and output of the device has a low VSWR 50 Ω match.
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 5 µA when the attenuator is off.
