SEMICONDUCTOR TECHNICAL DATA
The MRFIC Line
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.
• Usable Frequency Range 1.5 to 2.5 GHz
• High 1.0 dB Compression Point = 29 dBm (Typ)
• Low Transmit Insertion Loss = 0.75 dB (Typ)
• High Transmit to Receive Isolation = 22 dB (Typ)
• Single Control Pin for Easy Switching Signal Interface
• Low Current Drain = 300 µA (Typ) in TX, 45 µA (Typ) in RX
• Low Cost Surface Mount Plastic Package
• Order MRFIC1801R2 for Tape and Reel.

APPLICATIONS INFORMATION
The MRFIC1801 is a SPDT switch. A series–shunt pair of FETs are used in each path for improved isolation. The power handling
capability of the MRFIC1801 is determined by the difference between VDD and VSS. Typical operating conditions are VDD = 3.0
V and VSS = –2.5 V, but a negative VSS is not required. VSS can be grounded.
