RoHs Compliant GaAs, High Q Abrupt Tuning Varactors MA46600 Series V4 Features • • • • Constant Gamma Abrupt Junction: 0.5 Highest Q Large Capacitance Variation with Voltage Custom Tailored Designs Available on Request Description The MA46600 series of microwave tuning varactors is afamily of abrupt junction gallium arsenide devices featuring Q factors in excess of 8000. This series is specifically designed for broadband high Q 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 capacitance 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 ceramic packages as well as in chip form. Absolute Maximum Ratings @ TA=+25 °C Parameter Absolute Maximum Operating Temperature -65°C to +175°C Storage Temperature -65°C to +200°C Reverse Voltage Breakdown Voltage Power Dissipation (derate linearly to zero at 200°C) Cj < 1.0 pF max. @ 50 mW Cj ≥ 1.0 pF min. @ 100 mW 1. Operation of this device above any one of these parameters may cause permanent damage.The maximum storage and Common Case styles 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. 1 M/A-COM Inc. and its affiliates reserve the right to make changes to the product(s) or information contained herein without notice.

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 ordering, specify the desired case by adding the case designation 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 CT14 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.
