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.
