Avantel softech ltd. Designs & manufactures repeaters, filters, combiners & amplifiers to enhance the capacity & coverage of wireless communication networks for use in gsm, cdma & 3g networks. Power amplifiers can be divided into cw amplifiers and pulsed amplifiers depending upon their application. Further depending upon their output level they are classified as low power amplifiers, medium power amplifiers and high power amplifiers. The parameters that characterize, in general, the overall performance of an amplifier are gain, noise figure, gain flatness, output power at 1 db gain compression point, input / output vswr, saturation output power, third order intercept point, dynamic range etc.
