These diodes offer high Q (up to 4000) permitting excellent tuning performance from 1 VHF through Ka band. Each part in this series Absolute Maximum Ratings exhibits the large change in capacitance versus bias T =+25 C (Unless Otherwise Noted) A voltage characteristic of hyperabrupt junctions. The standard capacitance tolerance is 10%, with tighter Parameter Absolute Maximum tolerances available. Capacitance matching at one or more bias voltages is also available. All diode Reverse Voltage Breakdown Voltage types are available in a wide selection of ceramic packages and in chip form. The constant gamma Operating Temperature -65C to +175C value of 1.0, 1.25 & 1.5 available with these diodes Storage Temperature 65C to +200C enables the circuit designer to produce significant improvements in circuit performance. Constant 1. Operation of this device above any one of these parameters gamma tuning varactors permit more linear VCO may cause permanent damage.The maximum storage and frequency tuning than do conventional hyperabrupt operating temperature of the plastic ODS-1088 case style is tuning varactors. These varactors are particularly 125C. well suited for use in voltage tuned filters, analog phase shifters, and modulator circuits.

All GaAs tuning varactors are available in chip form. Please contact factory for part number information. 3. The values guaranteed for gamma are measured on unpackaged chips. The total capacitance versus bias voltage curve will deviate slightly from the chip capacitance versus bias voltage curve due to the package parasitic capacitance (Cp). 4. Case parasitics (Cp and Ls) are given for most case styles along with case outlines in the appendix. 5. Closer tolerances are available upon request. 6. Reverse voltage (Vbr) is measured at 10 microamps. 7. The total capacitance and capacitance ratios shown are for diodes housed in case style 30 with Cp= 0.170 pF unless otherwise specified. Other case styles will result in different values. 8. This part is offered in die form, shipped in a gel pack. The part number is MAVR-046479-01340G. 22 2 M/A-COM Technology Solutions Inc.
