The MRFIC0001 is an integrated Quadrature Modulator designed for operation in the 50 to 260 MHz frequency range. The design utilizes Motorola’s advanced MOSAIC 3 silicon bipolar RF process to yield superior performance in a cost effective monolithic device. Applications include DQPSK for PDC, NADC, and PHS; GMSK for GSM and DCS1800; and QPSK for CATV.
The MRFIC0001 is an integrated quadrature modulator designed for operation in the 50 to 260 MHz frequency range. It targets applications such as DQPSK for PDC, GMSK for GSM/DCS1800, and QPSK for CATV.
