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 and MRFIC1808DM are two–stage low noise amplifiers in
low–cost SO–8 and Micro–8 packages. 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 Rx Enable pin allows
for very low standby current while the system is in transmit mode.
