Description

The TST0951 is a low-noise amplifier (LNA) in SiGe technology. This LNA offers the possibility to apply a gain switching through a control input pin, and provides a power-down mode function for extending the battery operation time.

In low-gain mode, the output drive capability is not reduced, resulting in improved intermodulation performance. The nominal gain is very precise and has max. ±1.0 dB gain variation over full temperature range and supply-voltage range.

Electrostatic sensitive device. Observe precautions for handling.
