| High Dynamic Range LNA, 1800 - 2200 MHz V 1.00 AM50-0012 Features * * * * * Ideal for Base Station Applications High Gain: 19 dB @ 2000 MHz Low Noise Figure: 1.4 dB High Input IP3: +13 dBm Small Footprint 3mm FQFP-N Package 3mm, 12-Lead, FQFP-N Description M/A-COM's AM50-0012 is a high dynamic range, GaAs MMIC, low noise amplifier in a low-cost small footprint 3mm FQFP-N package. It employs external matching to obtain optimum noise figure and intercept performance. The AM50-0012 is operated with a supply voltage of +5V. The AM50-0012 is ideally suited for use where low noise figure, high gain, and high dynamic range are required. Typical applications included receiver front ends in TDMA, CDMA, and DCS base stations. It may also be used as an IF amplifier in certain other communication systems. The AM50-0012 is fabricated using a low-cost 0.5-micron gate E-D SAGFET GaAs process. This process features full passivation for increased reliability. The AM50-0012 is 100% RF tested to ensure performance specification compliance.
