MA46H201-1056

Overview

The MA46H201-1056 is a surface mount gallium arsenide tuning varactor diode from the MACOM MA46 Series. It features a hyperabrupt junction with a constant gamma of 1.25, operating within a reverse voltage range of 2 to 20 volts. The device provides a total capacitance of 0.9 pF at 4 V and 1.1 pF at 2 V, yielding a capacitance ratio of 4.1. It maintains a minimum quality factor of 3000 at 4 V. The component is housed in the hermetic ODS-1056 case style, which supports screening to JANTX levels.

Feature Summary

• Hyperabrupt junction design with constant gamma of 1.25 for wide bandwidth tuning applications
• Hermetic ODS-1056 package construction suitable for high reliability environments
• Silicon nitride protected junctions ensuring low leakage current and high stability

Applications

• Wide bandwidth Voltage Controlled Oscillators (VCOs)
• Voltage Tuned Filters (VTFs) requiring optimal tuning range and quality factor combination

Procurement Notes

Verify the specific ordering suffix to confirm the package style, as the base model number requires a case designation such as -1056 or -1088 to define the physical housing. Confirm that the required screening level matches the hermetic capabilities of the selected case style. Ensure the application bias voltage remains within the specified 2 to 20 volt range for proper gamma performance.

Selection Notes

Select this component when a wide tuning range combined with a high quality factor is necessary. The 1.25 gamma characteristic distinguishes it from the 0.75 and 1.5 gamma families, offering a larger capacitance ratio than other GaAs varactors. Consider the ODS-1056 package if hermetic sealing is required for the target environment.

Part Context

This part 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 from 2 to 20 volts. They are designed to provide the largest capacitance ratio among the available GaAs varactor families while maintaining a high quality factor.
