Many combinations of mechanical tuning range and output power are possible.These versions are representative examples. Many requirementsbeyond these standard ranges can be met. Contact Millitech for more information. Power output and tuning range are critically dependent on the actual centerfrequency in this frequency range. Please contact Millitech for details. Please contact Millitech for wider tuning options. Gunn Voltage is determined at test and can vary from 4.0 to 6.0V. Optionalvoltage regulator is available.NOTE: Please contact Millitech for a solution to your specific requirements.For more product information, search series GDM at www.millitech.com(GDV) Voltage – Controlled Gunn OscillatorElectrical Specifications (Vgunn = 4 to 6V, Vvaractor = Vgunn to -20V, Igunn = 1.0A(typ))Model Number GDV-28 GDV-22 GDV-19 GDV-15 GDV-12 GDV-10Frequency Range (GHz) 26.5-40 33-40 40-50 40-50 50-60 50-60 60-75 60-75 75-90 75-90 90-100Typical frequency stability (MHz/°C) 2 2 3 3 4 4 4 4 5 5 5Typical power stability (dB/°C) 0.03 0.03 0.03 0.03 0.03 0.03 0.04 0.04 0.04 0.04 0.04Narrow Tuning Version (±100 MHz) Available power (dBm) (min) 23 23 21 21 19 19 17 17 15 15 13Moderate Tuning Version (±500 MHz) Available power (dBm) (min) 21 21 19 19 17 17 15 15 13 13 12 Center frequency tolerance ±100 unless otherwise specified.
