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.
