S510069-28Z Datasheet, PDF (1/8 Pages) SIRENZA MICRODEVICES – AGC Amplifier

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.
