Product Description
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 50Ω 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 5µA when the attenuator is off.
