(Unless Otherwise Noted) Description The MA46580,MA46585 and MA46H130 series of beam lead constant gamma tuning varactors are hyperabrupt junction gallium arsenide diodes with a constant gamma of 1.0 or 1.25. The high Q values and the elimination of package parasitics make these varactors very attractive for voltage controlled oscillators that require linear tuning. These tuning diodes are useful at frequencies as high as 40 Ghz. Parameter Absolute Maximum Reverse Voltage 18V Operating Temperature -65°C to +150°C Storage Temperature -65°C to +200°C Power Dissipation 25mW at 25 °C Beam Strength 10 grams minimum 1. Operation of this device above any one of these parameters may cause permanent damage. Applications These beam lead constant gamma tuning varactors are particularly useful in broadband VCO’s, where linear frequency tuning is an important feature. They are also very useful for FM modulating a source for telecommunication transmitter and in many cases such circuits can be designed without a linearization circuit. The beam lead design eliminates almost all of the package parasitics resulting in improved linearity of the junction capacitance change with applied reverse bias voltage. This improves tracking between diodes and can improve VCO linearity.
