The MRFIC Line
900 MHz Driver and Ramp
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/turn-
on time. Also, an on-board inverter is included to provide complementary
control for an antenna switch, such as the MRFIC2003. The design utilizes
Motorola鈥檚 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.
