The MRFIC2004 is an integrated Driver and Ramp designed for transmitters operating in the 800 MHz to 1.0 GHz frequency range. The Ramp is an integrator which can be used for burst control for TDD/TDMA systems. The Driver uses a cascode configuration for high gain and reverse isolation. A power down control is provided to minimize current drain with minimum recovery/turnon time. Also, an on-board inverter is included to provide complementary control for an antenna switch, such as the MRFIC2003. The design utilizes Motorola’s advanced MOSAIC 3 silicon bipolar RF process to yield superior performance in a cost effective monolithic device. Applications for the MRFIC2004 include CT1 and CT2 cordless telephones, GSM, remote controls, video and audio short range links, low cost cellular radios, and ISM band transmitters.
