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. 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.
