The MRFIC Line
1.8 GHz Antenna Switch
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.
