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 50
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
μ
A
when the attenuator is off.
