Preliminary
Product Description
Sirenza Microdevice's S510069-28Z is a Variable Gain Amplifier (VGA), designed for use in Digital and Analog RF tuners and linear applications requiring IF signal amplification and control before the A/D converter. This IC consists of two amplifier stages that are AC coupled. Gain control is delayed between the two stages for minimal noise figure impact over the first 30 dB of gain control while maintaining excellent linearity performance. This product is RoHS compliant.
