RF2420

RF2420 9 Typical Applications Power Control in Communication Systems CMOS Compatible Programmable Attenuators Commercial and Consumer Systems Portable Battery-Powered Equipment PROGRAMMABLE ATTENUATOR Product Description The RF2420 is a multistage monolithic programmable attenuator. The device is built using an advanced Gallium Arsenide process technology and has an attenuation programmability over a 44dB 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 Ω match. This unit is intended for use in systems that require RF transmit power control by digital means. Typical applications are in dual mode IS-54/55 compatible cellular transceivers and TETRA systems. No negative supply voltages are required. 0.157 0.150 -A0.008 0.004 0.393 0.386 0.018 0.014 0.050 0.244 0.229 8° MAX 0° MIN 0.009 0.007 0.068 0.053 NOTES: 1. Shaded lead is Pin 1. 2.
