| Low Noise GaAs MMIC Amplifier 7.5 - 12 GHz Features q q q q q q MAAM71200-H1 V 2.00 CR-16 2.7 dB Typical Noise Figure 15.5 dB Typical Gain Single Bias Supply Low Current Consumption DC Decoupled RF Input and Output Ceramic Package Description M/A-COM's MAAM71200-H1 is a wide band, low noise GaAs MMIC amplifier enclosed in a leadless ceramic package1. The MAAM71200-H1 is a packaged version of M/A-COM's MAAM71200 low noise MMIC amplifier chip. The fully monolithic design operates in 50 ohms without the need for external components. Dimensions are in inches. The MAAM71200-H1 is ideally suited for microstrip assemblies where wire or ribbon bonds are used for interconnects. Typical applications include radar, EW and communication systems. The MAAM71200 is fabricated using a mature 0.5-micron gate length GaAs process for increased reliability and performance repeatability.

Operation of this device outside any of these limits may cause permanent damage 1. Case must be electrically connected to RF and DC ground. 2.The RF bond inductance from the transmission line to the package is assumed to be 0.25 nH. Variations in bond inductance will result in variations in VSWR and gain slope. A small capacitive stub may be needed depending on the inductance realized in the final assembly. 3.Nominal bias is obtained by setting V DD = 4 volts. 4.Increasing VDD from 4 volts to 6 volts increases output power and high frequency bandwidth.
