QPB8808 20dB CATV +12V Power Doubler Product Description The QPB8808 is an ultra-linear, QFN GaAs amplifier MMIC intended for output stage amplification in CATV infrastructure applications. The device features a push-pull cascode design which provides flat gain along with ultra-low distortion, making it 40 Pin 5x7 mm QFN Package ideal for use in CATV distribution systems requiring high output power capability. Product Features The QPB8808 draws approximately 525mA from a single 50 1218 MHz Bandwidth +12V supply providing ~20 dB gain with excellent linearity. Excellent High Output Linearity at Reduced Supply Users may adjust the bias current with external voltage Voltages enabling the QPB8808 to be used in applications such as Ultra-Low CSO/CTB/XMOD doublers or for lower power system applications. Low Noise The QPB8808 is packaged in an industry standard 40 pin Excellent Input/Output Return Loss 5 x7 mm QFN package with exposed paddle (EP) beneath High Gain, 20.6 dB typ. at 1218 MHz the device for thermal and electrical grounding Settable bias current Compact 5 X7 mm QFN Package +12V Supply Voltage 525 mA Operating Current Functional Block Diagram Applications HFC Nodes CATV Line Amplifiers Head End Equipment 50 1218 MHz 75 Amplifier Ordering Information Part No. Description QPB8808SQ Sample bag 25 pcs QPB8808SR 7 Reel with 100 pcs QPB8808TR13 13 Reel with 2500 pcs QPB8808PCK401 EVB with 5-piece sample bag Data Sheet Rev E, Nov 10, 2016 Subject to change without notice 1 of 6 www.qorvo.com QPB8808 20 dB CATV +12 V Power Doubler Absolute Maximum Ratings Recommended Operating Conditions Parameter Value /Range Parameter Min Typ Max Units Storage Temperature 40 to 100C Device Voltage (VDD) +12 V 6 Operating Temperature 40 to 85C Tj for >10 hours MTTF 150 C Device Voltage (V ) +18V Electrical specifications are measured at specified test conditions.
