| LEAD FREE Broadband CATV Amplifier 50 - 1000 MHz Features * * * * * * * * * 75 Ohm Input / Output Match CTB: -80 dBc Noise Figure: 2.7 dB Gain: 14.8 dB Lead Free SOT-89 Package 100% Matte Tin Plating over Copper Halogen-Free "Green" Mold Compound RoHS Compliant and 260C Re-flow Compatible Lead Free Version of MAAMSS0031 MAAMSS0041 V1 Functional Schematic GND Description M/A-COM's MAAMSS0041 CATV amplifier is a GaAs MMIC which exhibits low distortion in a lead-free surface mount plastic package. The MAAMSS0041 employs a monolithic single stage design featuring a convenient 75 ohm input/output impedance that minimizes the number of external components required. The MAAMSS0041 provides low noise and high linearity. It is ideally suited for set top boxes, home gateways, and other broadband internet based appliances. The MAAMSS0041 is fabricated using M/A-COM's PHEMT process to realize low noise and low distortion. The process features full passivation for robust performance and reliability.

LEAD FREE Broadband CATV Amplifier 50 - 1000 MHz Enhanced Input Return Loss (IRL) and Gain Flatness An enhanced input return loss and improved gain flatness circuit has been developed for applications where those parameters are key to system performance. Adding a series inductor, L3, to the input, a shunt capacitor, C5, to the output, and changing the bias inductor, L1, value will improve the input return loss to 25 dB typical from 50 to 1000 MHz. The gain flatness will also improve to less than 0.3 dB from 50 to 1000 MHz.
