Description
The 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 Ω input/output
impedance that minimizes the number of external
components required.

3. Exceeding any one or combination of these limits may cause
permanent damage to this device.
4. M/A-COM does not recommend sustained operation near these
survivability limits.
5. These operating conditions will ensure MTTF > 1 x 106 hours.
6. Junction Temperature (TJ) = TC + Өjc * (V * I)
Typical thermal resistance (Өjc) = 75° C/W.
a) For TC = 25°C,
TJ = 85°C @ 8 V, 100 mA
b) For TC = 85°C,
TJ = 139 °C @ 8 V, 90 mA
