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.

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.
