Advance Information
The MRFIC Line
1.9 GHz GaAs Downconverter
Designed primarily for use in wireless Personal Communication Systems
(PCS) applications such as Digital European Cordless Telephone (DECT),
Japan’s Personal Handy System (PHS), and the emerging North American
systems. The MRFIC1814 includes a low noise amplifier and downmixer in a
low-cost TSSOP–16 package. The integrated circuit requires minimal off-chip
matching while allowing for the maximum in flexibility and efficiency. The mixer
is optimized for low–side injection and offers reasonable intercept point as well
as high efficiency with 9 dB of conversion gain. Image filtering is implemented
off-chip to allow maximum flexibility. CMOS compatible ENABLE pins allow
standby operation where the current drain is less than 0.1 mA.
Together with the rest of the MRFIC180X series, this GaAs IC family offers
the complete transmit and receive functions, less LO and filters, needed for a
typical 1.8 GHz cordless telephone.
