GT-1000A Microwave Power Amplier
2 GHz to 20 GHz
Broadband High-Power Instrumentation Amplier
34682 Rev. I / US090707
GT-1000A Microwave Power Amplier
Advanced Amplier Technology
• 2 to 20 GHz eliminates band switching, reduces cost and complexity
Solid-state technology for low noise, high reliability and long life •
Ideal for EMC, Wireless Communications and Defense EW applications •
The Giga-tronics GT-1000A Microwave Power Amplifier incorporates the CAP Wireless patented Spatium™
spatial combining architecture solid-state amplifier. The Spatium™ technology amplifier is based on a solidstate 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.
The Giga-tronics GT-1000A Microwave Power Amplifier provides 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). The GT-1000A features low noise figure, low harmonics and spurious content,
and is highly tolerant to load mismatch.

GT-1000A Microwave Power Amplier
Advanced Amplier Technology
The Giga-tronics GT-1000A Microwave Power Amplifier offers linear high-power amplification across multi-octive
bands. It is ideal for testing in EMC, wireless communications applications and Defense EW systems. For EMI/EMC and
standards laboratories, the GT-1000A with 2 GHz to 20 GHz frequency range allows broadband testing without band
switching or swapping narrow band amplifiers resulting in faster and more accurate testing.
The amplifier can be used in wireless communications and component testing wherever a highly linear amplifier is
needed, such as testing RFICs and MMICs, or testing base station transmitters with high crest factor signals and high
peak-to-average power levels. The GT-1000A provides high power for testing limiters, step recovery diodes (SRD), or
driving traveling wave tubes (TWT), magnetrons and klystrons.
The microwave power amplifier with excellent pulse fidelity is ideal for many Aerospace and Defense applications,
including EW, ECM, ECCM, radar and satellite system signal simulation and testing. The GT-1000A 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.
The amplifier provides up to 40 dB of gain over the 2 GHz to 20 GHz frequency range. Gain is variable up to 10 dB
via a front panel knob. An optional coupler/detector is available for external power monitoring or for external leveling
a companion microwave signal generator. The GT-1000A can be paired with a Giga-tronics 2520B Microwave Signal
Generator, increasing the overall output power while preserving the synthesizer’s fast switching speed, modulation, and
high signal fidelity.
