The RF2420 is a multistage monolithic programmable
attenuator. The device is built using an advanced Gallium
Arsenide process technology and has an attenuation pro-
grammability over a 44dB range in 2dB steps. The atten-
uation is set by five bits of digital data. The input and
output of the device have a low VSWR 50
match. This
unit is intended for use in systems that require RF trans-
mit power control by digital means. Typical applications
are in dual mode IS-54/55 compatible cellular transceiv-
ers and TETRA systems. No negative supply voltages
are required.
