TST0951
SiGe 鈥?Low-Noise Amplifier (1900 MHz)
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.
鹵1.0
dB gain variation over full temperature range
and supply-voltage range.
Electrostatic sensitive device.
Observe precautions for handling.
