    • In a distributed IMPATT structure, power is coupled out through a side contact. That is, in previously proposed distributed IMPATT structures the gain medium (the active region of the IMPATT) operates as a transmission line. The prior art has attempted to couple output power from the gain medium through an end contact, i.e. through a contact which intercepts the primary direction of energy propagation of the active medium. In the present invention, a side contact extends along the whole active region in a direction which is parallel to the principal direction of propagation of the energy in the active medium. Thus, the side contact plus the active region together can be considered as a single transmission line.The present invention can be configured as an oscillator, amplifier, phase shifter, or attenuator. When configured as an oscillator, multiple short active regions can be sequentially coupled to a single long microstrip, which serves as the side contact for each of the active regions. This very simple power combining scheme provides extremely high power at millimeter wave frequencies.
    • 在分布式IMPATT结构中,通过侧面接触将电源耦合出来。 也就是说,在先前提出的分布式IMPATT结构中,增益介质(IMPATT的有源区)作为传输线工作。 现有技术已经尝试将来自增益介质的输出功率通过端接触,即通过拦截有源介质的能量传播的主要方向的接触来耦合。 在本发明中,侧接触沿着平行于活性介质中的能量的主要传播方向的整个有源区延伸。 因此,侧接触加上有源区域可以被认为是单个传输线。 本发明可以被配置为振荡器,放大器,移相器或衰减器。 当配置为振荡器时,多个短的有源区域可以顺序地耦合到单个长的微带,其用作每个有源区域的侧面接触。 这种非常简单的功率组合方案在毫米波频率下提供极高的功率。
