Overview
The MA46H202-1056T is a single hyperabrupt junction varactor diode manufactured by MACOM Technology Solutions. It utilizes Gallium Arsenide (GaAs) technology and is housed in the ODS-1056 surface mount package. The device features a minimum breakdown voltage of 30V, a reverse voltage rating of 22V, and a maximum forward current of 50mA. Nominal capacitance is specified at 3.3 pF with a minimum tuning ratio of 5.6 under test conditions of 2V/20V. It operates within a temperature range of -65°C to +150°C.
Feature Summary
- Hyperabrupt junction design for linear tuning applications
- Gallium Arsenide construction with silicon nitride protected junctions
- Hermetic ODS-1056 case style suitable for screening
Applications
- Voltage-controlled oscillators
- RF phase shifters
- Frequency multipliers
Procurement Notes
Verify the specific suffix 'T' against official documentation to confirm tape and reel packaging requirements. Ensure the selected component matches the required hermetic sealing standards associated with the ODS-1056 case style. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.
Selection Notes
Select this component when a high-quality factor and constant gamma characteristic are required for hyperabrupt tuning circuits. The 3.3 pF nominal capacitance and 30V breakdown voltage make it suitable for specific RF frequency ranges. Verify that the operating environment remains within the -65°C to +150°C junction temperature limits.
Part Context
This part belongs to the MA46H series of surface mount GaAs tuning varactors from MACOM. The series offers various junction types including abrupt and hyperabrupt configurations with different gamma values. The MA46H202 specifically provides a 1.5 constant gamma hyperabrupt junction optimized for wideband tuning performance.
Replacement Considerations
Consult the official MACOM substitution guide for verified equivalents. Generic replacements may not match the specific Gamma value or hermetic sealing capabilities of the ODS-1056 package.
