QuinStar
Technology's QCR series Gunn regulators are available in three
configurations. The Basic Compact regulator is available with and without AM or FM
modulation capability. Modulator Version includes both AM and FM capability. The Full
Feature Version offers numerous options, including AM/FM modulation. All versions
provide a low noise, low ripple, constant voltage output at a maximum of 2 Amps for bias
control. They also have short circuit and over-voltage/over-current protection to prevent
oscillator destruction by inadvertent application of a high voltage or current to which
Gunn oscillators are very sensitive. These regulator features are important for optimum
reliable operation of a Gunn diode oscillator. |
For
laboratory test stations it is sometimes useful, or required as in an HP8757 Scalar
Analyzer, to apply an AM or FM modulation. Provisions exist on the full feature regulator
for this modulation to be internally or externally supplied. In addition, the FM
modulation option can be used to phase lock the Gunn oscillator using a source locking
counter. |
