designed primarily for use in wireless personal communication systems (pcs) applications such as digital european cordless telephone (dect), japan's personal handy system (phs) and the emerging north american systems as a preamp for discrete or integrated downmixers. the MRFIC1808dm is a twostage low noise amplifier in a lowcost micro8 package. the amplifier can be matched to optimize gain or noise figure with simple offchip input matching. the design employs a novel stacked mesfet design which reuses bias current for the highest gain at minimal current. a cmos compatible rx enable pin allows for very low standby current while the system is in transmit mode. ? usable frequency range = 1.7 to 2.1 ghz ? 18 db typ gain ? 1.6 db typ noise figure ? simple offchip matching for maximum gain/noise figure flexibility ? high reverse isolation = 32 db (typ) ? single bias supply = 2.7 to 4.5 v ? low standby current = 8 m a (typ) ? low cost surface mount plastic package ? device marking = m1808 simplified block diagram this device contains 5 active transistors. rf in rf out ? motorola, inc. 1999 rev 6
