EE206 seas.upenn.edu Background. Thus, the circuit of Fig. 1 is a low pass filter. Figure 2 shows the frequency response of the magnitude and phase (Bode plot) of the transfer function. The bandwidth is defined as the frequency at which the gain has decreased by a factor √2 or (or where the magnitude has decreased by 3dB=20log (0.707)). Amplifier figures of merit Many amplifiers are ultimately slew rate limited (typically by the impedance of a drive current having to overcome capacitive effects at some point in the circuit), which sometimes limits the full power bandwidth to frequencies well below the amplifier's small signal frequency response. Valve RF amplifier (The "temperature" of this resistor for noise purposes is more close to the cathode temperature than to room temperature). Thus, the noise figure of tube amplifiers increases with frequency. At 200 MHz, a noise figure of 2.5 (or 4 dB) can be reached with the ECC2000 tube in an optimized "cascode" circuit with an optimized source impedance.
