MRFIC1854AR2

**Designed primarily for use in DECT, Japan Personal Handy System (PHS)

and other wireless Personal Communication Systems (PCS) applications. The MRFIC1807 includes a single–stage power amplifier and transmit/receive switch in a low–cost SOIC–16 package. The amplifier portion employs a depletion mode power GaAs MESFET and produces up to +27 dBm output with +19 dBm input. On–chip power control circuitry allows bias adjustment for optimum performance. The T/R switch is capable of handling up to +28 dBm through the transmit path without significant increase in insertion loss. The switch is controlled by CMOS logic level signals — no negative control voltage required. The MRFIC1807 is sized to be driven by the MRFIC1806 Driver/ Ramp IC.**

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.
