• Wide frequency coverage from UHF to VHF bands

Applications

• RF signal conversion in wireless communication systems
• IF processing in test and measurement equipment
• Frequency translation in industrial control circuits

Procurement Notes

Verify the specific datasheet version corresponding to the SRA-1H+ designation, as Mini-Circuits documentation may reference similar models like SRA-1H or SRA-1WH+. Confirm that the required frequency range up to 500 MHz aligns with system requirements. Ensure compatibility with the specified operating temperature limits of -55°C to +100°C for the intended environment. Cross-reference terminal count and package type with PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a double-balanced mixer is required for frequencies up to 500 MHz. Consider the surface-mount package for space-constrained designs. Evaluate the thermal performance against the maximum operating temperature of +100°C. Compare port isolation and conversion loss characteristics if detailed electrical data is available in the official specification sheet. Ensure the application does not exceed the maximum frequency limit.
