QuinStar Technology's series QTI CW injection-locked Gunn amplifiers
are alternatives to 3-terminal devices and IMPATT diode-based CW amplifiers, especially at
high millimeter wave frequencies. They are offered in the frequency range of 26.5-100 GHz
in four waveguide sizes with power levels up to 300 mW. The spectrum purity of the output
signal is the same as that of the input signal when the amplifier is injection-locked. |
In
the absence of an in-band input signal of sufficient power to attain injection-lock, there
is a free running output signal. The amplifiers are provided with integral circulators and
a DC voltage regulator, and an optional heater is available for improved temperature
stability. To achieve higher gain, broader locking bandwidth and higher output,
multi-stage and multi-diode configurations are available. |
