Renesas 提供数控的中频 (IF) 和射频 (RF) 可变增益放大器 (VGA)，这些放大器采用了FlatNoise™技术，当增益降低时其噪声不会恶化。 Renesas 的低噪声器件提高了服务质量 (QoS)，降低了系统对数据转换器的信噪比 (SNR) 要求，从而降低了系统成本。

一部分Renesas 的数字电压增益放大器采用Glitch-Free 专利技术，其目的是将其最高有效位 (MSB) 转变过程中产生的瞬时“毛刺”最大程度减少 95%，来消除发送和/或接收链路中因衰减设置而引起的过冲（毛刺）。 对于蜂窝基站和其他无线基础设施设备中的接收机和发射机而言，Renesas 的 IF VGA 和 RF VGA 是理想选择。

关于可变增益放大器（RF VGA 或 DVGA）

您可以 把RF 系统中的可变增益放大器 (RF VGA) 简单的理解为放大器（增益器件）和衰减器集成在同一封装中。 我们将使用数控的放大器称作数字可变增益放大器 (DVGA)。 这种器件既用在在发射机中也用在接收机中，目的是在信号链路中增加可调增益器件，这些器件可通过增加或减小衰减值实现增益调节（大小增益场景均可）。
