  amplifier chain
A 50 dB three stage power amplifier chain with an analog quadrature modulator and demodulator was used in the measurements as the device to be predistorted.
      
The performance of the predistorter was measured by driving a three-stage discrete power amplifier chain by a 2-tone test and a 3.84?MHz wide 3GPP WCDMA modulated signal.
      
We present a new method to determine the contribution of the IF-amplifier chain to the overall noise performance of an SE-based receiver.
      
As the beam is progressively amplified in the Nova amplifier chain, the bandwidth continues to narrow, but the spectrum remains Gaussian in shape.
      
First, an estimate for circuit losses must be obtained in order to estimate the requirements of the LO amplifier chain.

Based upon instantaneous output spectra of xenon flashlamp, a unique dynamic modeling program has been constructed to predict the gain performance of multisegment Nd:glass laser amplifiers. The model, which includes the all dynamic modulations from flashlamp discharging to laser outputting, may be used in laser amplifier system optimizations. The influences of disk thickness and Nd 2O 3 doping level on gain performance are studied with the modeling program. Under the condition of the same pumping lever, the stored fluence and the small signal gain are determined by the doping-thickness products(Nd ion concentration by slab thickness)in the MAS slab.
