MAAMSS0042 Broadband CATV Amplifier Rev. V4 50 - 1000 MHz Features Functional Schematic 75 Input / Output Match GGNDND -70 dBc CTB 3.0 dB Noise Figure 15 dB Gain Lead-Free SOT-89 Package Halogen-Free Green Mold Compound RoHS* Compliant and 260C Reflow Compatible Description The MAAMSS0042 CATV amplifier is a GaAs MMIC which exhibits low distortion in a Pin 1Pin 1 lead-free miniature surface mount plastic package. The MAAMSS0042 employs a monolithic single stage design featuring a convenient 75 input/ RFRF GGNDND RFRF OOUUTT ININ output impedance that minimizes the number of external components required. Pin Configuration The MAAMSS0042 provides low noise and high linearity. It is ideally suited for set top boxes, home Pin No. Pin Name Description gateways, FTTX, Drop Amplifiers, and other broadband internet based appliances. 1 RF RF Input IN 2 GND Ground The MAAMSS0042 is fabricated using M/A-COMs 3 RF RF Output / Drain Supply OUT PHEMT process to realize low noise and low distortion. The process features full passivation for robust performance and reliability. 3,4,5 Absolute Maximum Ratings Parameter Absolute Maximum 1,2 Ordering Information RF Input Power 10 dBm Voltage 10.0 volts Part Number Package Operating Temperature -20 C to +85 C MAAMSS0042 Bulk Packaging 6 Junction Temperature +150 C MAAMSS0042TR 1000 piece reel Storage Temperature -65 C to +150 C MAAMSS0042TR-3000 3000 piece reel 3.
