    摘要： A thermally stabilized cascode heterojunction bipolar transistor (TSC-HB) having the current and power generation regions in separate temperature zones, each transistor collector in a cold zone connected directly and individually to an emitter terminal of a corresponding transistor in a hot zone, thereby limiting the current available to the emitter of the transistor in the hot zone. Such an interconnection of transistors prevents the transistor in the hot zone from drawing more current from other transistor sources when increases in temperature occur. This achieves thermal stability and prevents the transistors from overheating and burning out.

    摘要： A two-port monolithic microwave amplifier, which uses a distributed negative resistance diode with gain (such as an IMPATT diode) as an active element. The diode is tapered (increasing in width but not in thickness) so that, as the RF signal propagates along the diode, it sees a wider and wider active diode region. This diode is operated in the power-saturated region, so that, as the RF signal propagates along the diode, terminal voltage remains essentially constant, but the RF current increases. This configuration is inherently undirectional.

    摘要： 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.

    摘要： A thermal and electrical interconnect for heterojunction bipolar transistors is disclosed wherein the interconnect is essentially comprised of gold and in thermal and electrical contact with each of the interdigitated emitter fingers and is capable of transporting heat fluxes between 0.25-1.5 mW/&mgr;m2. The interconnect is electrodeposited to form a low-stress interface with the emitter finger, thereby increasing the lifetime and reliability of the transistor.
