STVVGLNA：General-purpose, variable-gain, low-noise, RF amplifier for broadcast receiver applications

The STVVGLNA is a general-purpose, low-noise amplifier with a gain range of -17 dB to +15 dB. Its gain is regulated either autonomously by an integrated AGC loop or by software control.

It can be used, for example, as an input amplifier for a satellite set-top box.
