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 IP

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. Its 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.
