The MRFIC Line
1.8 GHz Upconverter
Designed primarily for use in DECT, Japan鈥檚 Personal Handy System (PHS),
and other wireless Personal Communication Systems (PCS) applications at 1.8
GHz, but also applicable to Industrial, Scientific and Medical (ISM) applications
at 2.5 GHz. The MRFIC1803 is a complete active upmixer, exciter amplifier, and
LO buffer amplifier in a low-cost SOIC-16 package. The low power consumption
design includes a single balanced active mixer, CMOS compatible receive and
transmit enable inputs, a buffer/exciter amplifier, and a buffered LO output
capable of driving the MRFIC1804 downconverter. IF, LO and RF ports are
matched to 50
鈩?/div>
and no off-chip baluns are required. With both TX and RX
enable pins low, the device is in standby mode and draws less than 0.3 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.
