A frequency compensated voltage divider or attenuator is a simple two-port RC network providing a fixed voltage division ratio or attenuation over a wide frequency range and not just at DC. Such networks are used where the part of the circuit loading the voltage divider output is capacitive. Fixed attenuators provide a constant level of attenuation; step attenuators offer precise control with. An attenuator is a passive component in high-frequency technology. Therefore, a frequency range is always specified for these components within. Attenuators are designed to change the magnitude of the input signal seen at the input stage, while presenting a constant impedance on all ranges at the attenuator input.
