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 MRFIC1808 is a two–stage low noise amplifier in a low–cost SO–8 package. The amplifier can be matched to optimize gain or noise figure with simple off–chip input matching. The design employs a novel stacked MESFET design which reuses bias current for the highest gain at minimal current. A CMOS compatible RECEIVE ENABLE pin allows for very low standby current while the system is in transmit mode.
