Digital/ Voltage-controlled Attenuators
Digital Attenuator:
A circuit that realizes signal attenuation by adjusting the signal level. Its working principle can be simply divided into two parts: a digital controller and an attenuator.
Voltage-controlled Attenuator:
A two-port network that adjusts the signal amplitude between the input and output ports by controlling the DC bias. It is widely used in RF and microwave systems. Its applications include gain control after LNA (Low Noise Amplifier) or PA (Power Amplifier), amplitude modulators, amplitude stabilization circuits in oscillators, automatic gain control systems, etc.
