QuinStar Technology’s QTM series of mechanically-tunable Gunn oscillators cover the frequency range of 18 to 150 GHz in nine waveguide bands. 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. If higher power is required,
QuinStar can provide an amplified version of the oscillators using power amplifiers. 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) are also available.
• High Output Power • Good Frequency Stability • Low AM and FM Noise
