Operation of this device above any one of these parameters may cause permanent damage.The maximum storage and vices featuring Q factors in excess of 8000. This operating temperature of the plastic ODS-1088 case style is series is specifically designed for broadband high Q 125C. tuning performance (up to 8000 at -4 volts and 50 MHz) from L through Ka band. Characteristics such as high reliability, low leakage and close capaci- Common Case styles tance tracking between diodes are typical of these devices. Standard capacitance matching is 10%, but closer matching is available upon request. All diode types are available in a wide selection of ce- ramic packages as well as in chip form. Applications The MA46600 series of tuning varactors can be used for both broad and narrow band tuning through Ka-band. Typical applications include solid state tuning of VCOs using transistors or Gunns as well as voltage tunable filters and amplifier circuits. The GaAs abrupt junction tuning varactors offer the highest Q of any tuning varactors and are utilized in high frequency applications where Q is premium. 134 Chip Specifications subject to change without notice. * Restrictions on Hazardous Substances, European Union Directive 2002/95/EC. 1 M/A-COM Technology Solutions Inc.

Capacitance is measured at 1 MHz on a bridge which has been balanced with shielded test holders connected in place but open circuited. 2. All GaAs tuning varactors are available in any case style shown in this bulletin as well as in chip form. When order- ing, specify the desired case by adding the case designa- tion as a suffix to the model number, i.e., MA46601-30. For example, a MA46601-30 specifies a 30 volt tuning diode in a case style 30 with a Ct -4v between .36 and .44 pF and a Q at -4 volts and 50 MHz 7500. The capacitance values and capacitance ratios are for case style 30. Other case styles or chips will have slightly different values. 3. All junctions are abrupt i.e., y = 0.50 .03. 4. Total capacitance ratios will vary with case choice due to differences in case capacitance (Cp). Figure 1 shows the ratio for the 30 case style. 5. Case parasitics (Cp and Ls) are given for most case styles. 6. Breakdown voltage (VB) is specified at -10 A. Specifications subject to change without notice. 2 M/A-COM Technology Solutions Inc.
