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 IP₃bypass

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.

Ordering Information

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.

Customer Defined

The PCB dielectric between RF traces and RF ground layers

should be chosen to reduce RF discontinuities between 50 Ω

lines and package pins. M/A-COM recommends an FR-4

dielectric thickness of 0.008” (0.2 mm) yielding a 50 Ω line

width of 0.015” (0.38 mm). The recommended metalization

thickness is 1 ounce copper.

Designer’s Kit AM55-0016SMB

The AM55-0016SMB Designer's Kit allows for immediate evaluation of M/A-COM's AM55-0016. The Designer’s Kit includes an

AM55-0016, an evaluation board and a floppy disk containing typical performance data and a DXF file of the recommended PCB layout.

The evaluation board consists of the recommended external surface mount circuitry, RF connectors and a DC multi-pin connector, all

mounted to a multi-layer FR-4 PCB. The AM55-0016SMB evaluation PCB is illustrated below with all functional ports labeled.
