Keiser, Optical fiber communications. The power and phase are adjusted by signal generator and phase shifter, the nonlinear component of injected signal and fundamental cancel one another in the output when they are equal in output power and opposite in phase.

Introduction Traveling wave tube TWT amplifier is widely used in the fields of communication, signal processing, radar, electronic warfare, and so forth. The IMD5 output power at the output of amplifier is written as. After being amplified, the IMD3 component at isand IMD5 component at is A IM3 signal of amplitude and phase at is injected into the amplifier together with the two-tone fundamental signal; the input signal is The IMD3 output power at the output of amplifier is expressed as The IMD5 output power at the output of amplifier is written as All parameters in 4 and 5 are known.

The input signal two-tone fundamental signal consists of two tones given by expressionthe amplitude and phase are andand the amplitude represents the power of signal in terms of power amplifier. Initial power and initial fundamental frequency represent input power and frequency of two-tone fundamental signal, they are variable, and the initial power and frequency variation of fundamental signal can influence output power of FUN, IMD3, and IMD5 under optimum injection and without signal injection.

The two-tone IM when the mopt is 0. The precision of input amplitude and phase was limited by signal generator and phase shifter to match the amount of suppression observed by means of simulation. This is contributed next odd order distortion after IMD3 which also has the by the number of IMD5 being greater than that of the tendency to fall in-band. The feedback second harmonic injection methods for simultaneous reduction of IMD3 and IMD5 in bisection laser diode have been studied [ 9 ], and a novel distortion reduction scheme for gain lever laser diodes has been presented [ 1011 ].

The 3D plot presents a funnel-shaped structure. Correspondence should be addressed to Kewen Xia ; nc. Imd5.5 configuration of the hybrid radio fibre systems. The amplifier nonlinearity can be expressed with a Taylor series equation [ 8919 ] connecting the output power to input signal by 1 ; are constants.

The value of TFR and IMD suppression achieved experimentally is limited by resolution bandwidths of signal generator and phase shifter; in particular, the suppression of IMD is particularly sensitive to the ijd5.15 adjustment of the phase shifter, and the amplitude and phase of injected signal can be tuned precisely to get simultaneous suppression.
