Description
M/A-COM’s AM55-0016 is a high dynamic range,
switchable low noise amplifier in a low cost, MSOP
8-lead, surface mount, plastic package. The design
utilizes a patented switching technique to provide a
low insertion loss, high input IP3 bypass state in
parallel with the high gain, low noise state.
The LNA employs external input matching to obtain
optimum noise figure performance and operating
frequency flexibility. The AM55-0016 also features
flexible biasing to control the current consumption
vs. dynamic range trade-off. It’s current can be
controlled over a range of 10 mA to 30 mA with an
external resistor.
Typical applications include receiver front ends in
cellular band CDMA handsets. It is also useful as a
switched gain block, buffer or driver in portable
cellular systems.
The AM55-0016 is fabricated using a low-cost 0.5-
micron gate length GaAs MESFET process. The
process features full passivation for increased
performance and reliability.
