Abstract
The present invention is a wideband temperature-dependent attenuator. In a preferred embodiment the attenuator is a modified Tee attenuator having first and second resistors connected in series at a first node and third and fourth resistors connected in shunt between the first node and ground. In a physical implementation of the attenuator, the third and fourth resistors are on opposite sides of the first and second resistors. Preferably, each of the four resistors is formed as a thick film resistor.
