SEMICONDUCTOR TECHNICAL DATA
The MRFIC Line
1.9 GHz GaAs
Low Noise Amplifier
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.
