Designed primarily for use in DECT, Japan Personal Handy System (PHS), other wireless Personal Communication Systems (PCS) applications, and 2.4 GHz ISM band applications. The MRFIC1801 is a single pole, double throw reflective antenna switch featuring low insertion loss and high power handling capability in a low-cost SOIC-8 package. The integrated circuit requires no off-chip matching and provides for easy control circuit interface. The high power handling capability allows application in higher power wireless systems than traditional GaAs antenna switches.
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.
