MRFIC1803

Designed primarily for use in DECT, Japan's 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 W 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.
