| MA46580 & MA46585 Beam Lead Constant Gamma GaAs Tuning Varactor Rev. V4 Features * Constant Gamma = 1.0 & 1.25 available * High Q (3000 minimum at 4V 50MHz) * Strong Beam Construction Absolute Maximum Ratings @ TA=+25 C (Unless Otherwise Noted) Parameter 1 Absolute Maximum (Minimum 10 gram beam strength) * Low Parasitic Capacitance * Close Capacitance tracking * Lead-Free (RoHs Compliant) equivalents available with 260C reflow compatibility Reverse Voltage Operating Temperature Storage Temperature Power Dissipation 18V -65C to +150C -65C to +200C 25mW at 25 C 10 grams minimum Description The MA46580 & MA46585 series beam lead constant gamma tuning varactors are hyper-abrupt 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. 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. Beam Strength 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.
