Technical Datasheet GT-1040A Microwave Power Amplifier 10 MHz to 40 GHz Broadband High-Power Instrumentation Amplifiers 34891 -Rev.A / US110718 Microwave Power Amplifier Advanced Amplifier Technology •• 10 MHz to 40 GHz eliminates band switching, reduces cost and complexity •• Solid-state technology for low noise, high reliability and long life •• Ideal for R&D Lab, ATE Systems, Wireless Communications and Defense EW applications The Giga-tronics GT-1040A Microwave Power Amplifier incorporates broadband MMIC-based architecture. These state-of-the-art amplifiers are based on solid-state parallel MMIC design with exceptionally wide bandwidth and high power. The unique circuit topology is highly reliable, with performance that excels where extremes of bandwidth and power are demanded. 34891-Rev. A/ US110718 The Giga-tronics GT-1040A Microwave Power Amplifiers provide excellent pulse fidelity, low intermodulation distortion, high linearity and superior gain flatness without the warm-up time, drift or aging issues of traveling wave tube amplifiers (TWTA). They feature low noise figure, low harmonics and spurious content, and are highly tolerant to load mismatch. 1 Microwave Power Amplifier Advanced Amplifier Technology The Giga-tronics GT-1040A Microwave Power Amplifiers offer linear high-power amplification across multi-octave bands. They are ideal for testing in R&D Lab, ATE Systems, wireless communications applications and Defense EW systems. The 10 MHz to 40 GHz frequency range allows broadband testing without band switching or swapping narrow band amplifiers resulting in faster and more accurate testing. The amplifiers can be used in wireless communications and component testing wherever a highly linear amplifier is needed. These microwave power amplifiers with excellent pulse fidelity are ideal for many Aerospace and Defense applications, including EW, ECM, ECCM, radar and satellite system signal simulation and testing. The GT-1040A is an ideal ATE system building block for boosting test signals to overcome cable and connector loss whenever long cable runs are needed in assembly bays, environmental test chambers or field locations. 34891-Rev. A/ US110718 The amplifier nominally provides 20 dB of gain over the 10 MHz to 40 GHz frequency range. The GT-1040A can be paired with a Giga-tronics 2440C 40 GHz Microwave Signal Generator or Giga-tronics 2540B 40 GHz Microwave Signal Generator, increasing the overall output power while preserving the synthesizer’s fast switching speed, modulation, and high signal fidelity. 2 Microwave Power Amplifier Technical Specifications Frequency Range GT-1040A 10 MHz to 40 GHz Output Power Output power is specified as minimum saturated power into 50 Ohm load with +5 dBm input, at 23°C ± 5°C Input power for normal operation should limited to +5 dBm maximum.
