Product Brief BGA728L7 A low-power, gain-step, broadband MMIC LNA for portable and mobile TV systems Applications Mobile TV function is a key feature for next generation cellular phones and portable devices such as notebook and multimedia players. Often a low noise amplifier (LNA) is required at the antenna input of these systems to improve the reception sensitivity and dynamic range. As a result, the users can enjoy premium picture quality. Low noise amplifier (LNA) for portable and mobile TV systems such as CMMB DMB-TH Based upon Infineon’s leading SiGe technology, the BGA728L7 offers very flat gain curve and best-in-class RF performance. The 1.8V capability, the mini-size leadless package and the extremely low external part count have made it an ideal choice for RF engineers to develop a power-and-space-saving tuner frontend within a short design cycle.
