MAAMSS0044 Push Pull CATV Amplifier Rev. V1 50 - 1000 MHz Features Functional Schematic Low Distortion N/C N/C N/C RF RF OUT1 OUT2 Low Noise Figure Push Pull Design Single Positive Supply N/C 1 N/C Lead-Free 4 mm 20-Lead PQFN package N/C N/C Halogen-Free Green Mold Compound RoHS* Compliant and 260C Reflow Compatible N/C N/C N/C N/C Description M/A-COMs MAAMSS0044 is a GaAs PHEMT MMIC N/C N/C amplifier in a lead-free 4 mm 20-lead PQFN package. The MMIC design is configured as a pair of cascode PHEMT amplifiers for broadband N/C N/C N/C RF RF IN1 IN2 performance. It is designed for integration in a 75 push-pull, low distortion, amplifier circuit. The 3 Pin Configuration device is ideally suited for use in CATV, FTTX, DBS, and HDTV applications where low noise figure and Pin No. Pin Name Description low distortion are required. 4 1 N/C No Connection 2 N/C No Connection 3 N/C No Connection 1,2 4 N/C No Connection Ordering Information 5 N/C No Connection Part Number Package RF 6 RF Input 1 IN1 MAAMSS0044 Bulk Packaging 7 N/C No Connection MAAMSS0044TR 1000 Piece Reel 8 N/C No Connection 9 N/C No Connection MAAMSS0044TR-3000 3000 Piece Reel 10 RF RF Input 2 IN2 Sample Board MAAMSS0044SMB 11 N/C No Connection 50 - 1000 MHZ Tuning 12 N/C No Connection 1.

Proper ESD control Storage Temperature -65C to +150C techniques should be used when handling these devices. 5. Exceeding any one or combination of these limits may cause permanent damage to this device. 6. M/A-COM does not recommend sustained operation near these survivability limits. 6 7. These operating conditions will ensure MTTF > 1 x 10 hours. 8.
