Product Description
The RF2410 is a multistage monolithic programmable
attenuator. The device is built using a Gallium Arsenide
process technology and has an attenuation programma-
bility over a 38dB range in 2dB steps. The attenuation is
set by five bits of digital data. The input and output of the
device have a low VSWR 50鈩?match. The RF output can
drive up to +10dBm. This unit is intended for use in sys-
tems that require RF transmit power control by digital
means. A typical application is in dual mode IS-54/55
compatible cellular transceivers. No negative supply volt-
ages are required, and the unit has a power down feature
which reduces the current consumption to less than
0.5mA.
