QuinStar Technology's QTM series of mechanically-tunable
Gunn oscillators cover the frequency range of 18 to 100 GHz in seven waveguide
bands (above 100 GHz we offer fixed frequency or bias tuned Gunn oscillators). They
combine a high-Q resonant circuit with either a GaAs or InP Gunn diode. Typically, InP
diodes are used for high-power applications at the higher frequencies. Each oscillator has
an internal low-frequency bias circuit with an oscillation suppression network and
over-voltage protection. Standard units are rated over 0 to +50° C operating temperature
and incorporate a screw tuner with a reliable self-locking feature. |
Gunn
oscillators can be provided with broader tuning ranges, higher power levels, micrometer
tuners, temperature controlled heaters, integral isolators, voltage regulators, modulators
and injection-locking capability.
Series QTM oscillators provide
a small bias tuning of operating frequency. Often, bias tuning can be used in place of varactor-tuning (series QTV). Phase-locked oscillators (Series QPL) and injection-locked oscillators (Series
QTI) are also available. |
