Abstract

PURPOSE:To carry out the temperature compensation for oscillation frequency econimically and simply by inserting a resistance in series into bias supplying source equipped on the external of an oscillator. CONSTITUTION:Cavity wall 3, which is made from metals, consisting of cavity 2 is equipped and metal post 4 which applied biases to Gunn diode 1, which is insulated in series from cavity wall 3 and earthed in high frequency, are also equipped with the oscillator. When a bias is applied to Gunn diode 1 through series resistance 8, a micro wave is outputted from circular or square-shape hole 6 called as an iris. In case of defining that the voltage of power source 5 is VB, the voltage applied to Gunn diode 1 is VS, resistance value of resistance 8 is R, and bias current is IB, VB=V'B-IBR is formed, and when the formula is differenciated by a temperature, dVB/dV=-RdIS/dT=RK is formed. When dIB/dT=-K, df/dVB=P, df/ dT=df/dVB.dVB/dT=PRK>O is formed. When K=1.25mA/ deg.C, P=4000kHz/V and R=10OMEGA for example, df/dT=50KHz/ deg.C is formed, so that the temperature compensation of 50KHz/ deg.C is available by means of applying the resistance of 10OMEGA.
