MA46H200-1056

Overview

The MA46H200-1056 is a surface mount gallium arsenide tuning varactor featuring a hyperabrupt junction with a constant gamma of 1.25 from 2 to 20 volts. It provides a total capacitance of 0.5 pF at 4 V reverse bias and 0.7 pF at 2 V, yielding a capacitance ratio of 3.0. The device guarantees a minimum quality factor of 1500 at 4 V reverse voltage. Electrical specifications include a breakdown voltage of 22 V minimum at 10 µA and a maximum reverse current of 100 nA at 16 V. The component is housed in the hermetic ODS-1056 ceramic package.

Feature Summary

• Hyperabrupt junction design optimized for wide bandwidth applications
• Hermetic ODS-1056 case style suitable for screening to JANTX levels
• Silicon nitride protected junctions ensuring low leakage current and high reliability

Applications

• Wide bandwidth Voltage Controlled Oscillators (VCOs)
• Voltage Tuned Filters (VTFs) requiring wide tuning range
• Frequency-selective surfaces utilizing inductive shunting

Procurement Notes

Verify the specific ordering suffix matches the required package style. The -1056 designation indicates the hermetic ODS-1056 case. Confirm that the application environment remains within the specified operating temperature range of -65°C to +150°C. Ensure bias voltages do not exceed the absolute maximum ratings to prevent permanent damage.

Selection Notes

Select this part when a combination of very wide tuning range and high quality factor is required. The 1.25 gamma characteristic offers the largest capacitance ratio among the GaAs varactor families. Consider the ODS-1088 package if non-hermetic surface mount packaging is preferred instead of the hermetic option.

Part Context

This component belongs to the MA46H200 through MA46H204 family of surface mount GaAs tuning varactors. These devices are characterized by hyperabrupt junctions with a constant gamma of 1.25. They are designed to provide the optimum combination of wide tuning range and high quality factor for demanding RF applications.
