RoHS Compliant Low Noise GaAs MMIC Amplifier 1.2 - 1.75 GHz Features • • • • • • MAAM12000-A1 V4 Schematic Low Noise Figure: 1.35 dB High Gain: 26 dB No External Components Required DC Decoupled RF Input and Output Lead-Free 8-Lead Ceramic Package RoHS* Compliant and 260°C Reflow Compatible Typical Biasing Configuration and Functional Block Diagram GND GND RF IN Description M/A-COM’s MAAM12000-A1 is a wide band, low noise, MMIC amplifier housed in a lead-free, small 8-lead ceramic package. It includes two integrated gain stages and employs series inductive feedback to obtain excellent noise figure and a good, 50-ohm, input and output impedance match over the 1.2 to 1.75 GHz band. The MAAM12000-A1 is fully monolithic, requires no external components and is provided in a low-cost, user-friendly, microwave package. The MAAM12000-A1 is ideally suited to receivers in GPS and DGPS applications and operates over both the L1 and L2 frequency bands. Because of its wide bandwidth, the MAAM12000-A1 can also be used as a driver, buffer or IF amplifier in numerous commercial and government system applications that require high gain, excellent linearity and low power consumption.
