自美国无线电公司实验室在1967年发现TRAPATT模式后,在器件研制和实际应用研究方面已取得很大进展,现在正致力于研制在更高频率下获得更大功率和更高效率的TRAPATT放大器。由于它的迅速发展和它对核辐射不敏感,它已成为雷达系统中有希望的一种固体微波源。目前TRAPATT二极管的脉冲宽度限于0.5微秒,最大占空因数为1％的数量级。但相控阵雷达要求脉宽为5～100微秒,占空因数高达10％以上。美国无线电公司最近在器件和电路工艺方面获得了新的进展,已获得高达50微秒的脉宽,在S波段的输出功率为100～150瓦。全部用微波集成电路并用氧化铝和聚四氟乙烯玻璃纤维
Since the discovery of the TRAPATT mode in 1967, the Radio Laboratory of the United States has made great strides in device development and practical application research and is now working on a TRAPATT amplifier that achieves more power and efficiency at higher frequencies. Due to its rapid development and its insensitivity to nuclear radiation, it has become a promising source of solid microwaves in radar systems. At present, the pulse width of the TRAPATT diode is limited to 0.5 microseconds and the maximum duty cycle is on the order of 1%. Phased array radar, however, requires a pulse width of 5 to 100 microseconds and a duty cycle of up to 10%. American Radio has recently made new advances in device and circuit technology with pulse widths up to 50 microseconds and output powers in the S band of 100 to 150 watts. All with microwave integrated circuits and with alumina and Teflon glass fibers
