1MHz-2000MHz ALC AGC RF power transfer radio attenuator AGC
The main application for adjusting the amplitude of the RF signal of the RF circuit, AGC, ALC and other circuits, or on the front as the output amplifier stage power adjustment. Circuit by adjusting a precision potentiometers to adjust the amount of attenuation of the input and output terminals, thereby controlling the amplitude of the output signal. In the radio frequency circuit is widely used!
You can also cascade multiple attenuators to increase the amount of attenuation to 80-90dB or more! Weak signal for testing! Such as receiver sensitivity! \
