MRFIC1808中文资料1.9 GHz GaAs Low Noise Amplifier数据手册恩XP规格书

描述 Description

Overview 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.
