Description:
Designed specifically for single voltage operations (i.e. no negative voltage is required), the MwT-A989SB is a high linearity GaAs
MESFET device in low cost SOT89 package that is ideally suited for high dynamic range LNA applications. The applications include
2G, 2.5G, and 3G wireless infrastructure standards, such as GSM, TDMA, cdma, Edge, cdma2000, WCDMA, TD-SCDMA, and UMTS
base stations. This product is also ideal for high data rate wireless LAN infrastructure applications, such as high QAM rate 802.11
WiFi and 802.16 WiMax base stations and APs (Access Points). In additional, the product can be used for point-to-point microwave
communications links. The third order intercept performance of the MwT-A989SB is excellent, typically 14 dB above the 1 dB power
gain compression point. The NF is as low as 0.6 dB at 900 MHz. The chip is produced using MwT's proprietary high linearity device
design and process with reliable metal system. All chips are passivated using MwT's patented "Diamond-Like Carbon" process for
increased durability.
