PMTO-8R8G9R56G-CD-1 Active

Medium Power X-band Gunn-Effect Oscillator

Quantic PMI Model No. PMTO-8R8G9R56G-CD-1 is a temperature stabilized output medium power X-band Gunn-effect Oscillator for use as an RF simulator signal generator. This unit contains a precision voltage regulator, a low-noise gunn-effect oscillator mounted on a thermal platform with integral load isolators for each of the RF outputs and a solid-state proportional temperature controlled along with associated heaters and temperatures sensor. This unit shall meet all requirements listed below after a 15-minute warm up with all outputs terminated in a 50 Ohm load with a VSWR of 1.5:1 for all phases over the operating range. The unit shall be capable of withstanding, without damage or permanent degradation of performance, any temporary extreme load condition, i.e. short or open circuit.
