Ku band amplifier design for satcom systems

Medium-power Ku Band amplifier block is designed for Satcom applications. The amplifier is low-power, and intended for driver amplifier or first-stage amplifier after frequency up-conversion in block-up conversion unit. Two-stage amplifier has 18dB gain and 0.9dB maximum ripple in 13.75-14.5 GHz band which is designated as the transmit band of Ku band satcom systems. NE3511 HJ-FET transistors are used for the amplifier design, and additionally, Ku band bandpass filter is designed.
