MRFIC1806

( DataSheet : www.DataSheet4U.com ) MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MRFIC1806/D The MRFIC Line 1.8 GHz PA Driver/Ramp Designed primarily for use in DECT, Japan Personal Handy System (PHS), and other wireless Personal Communication Systems (PCS) applications. The MRFIC1806 includes a two stage driver amplifier and transmit waveform shaping circuitry in a low–cost SOIC–16 package. The amplifier portion employs depletion mode power GaAs MESFETs to produce +21 dBm output with 0 dBm input. The ramping circuit controls the burst–mode transmit rise and fall time and is adjustable through external components. This circuitry also places the amplifier in standby during TDMA receive mode. The MRFIC1806 is sized to drive the MRFIC1807 PA/Switch. Together with the rest of the MRFIC1800 GaAs ICs, this family offers the complete transmit and receive functions, less LO and filters, needed for a typical 1.8 GHz cordless telephone.
