ABSTRACT:
A temperature regulated feed forward amplifier for use in broad bandwidth cable communications applications, includes an IC amplifier, a fixed voltage power supply for the IC amplifier, temperature sensing circuitry for detecting temperature variations from a preselected reference temperature and regulating the voltage from the fixed voltage power supply to maintain the gain and resultant phase of the amplifier relatively uniform over the bandwidth and over a range of temperatures.
