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

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.
