RMK-3-212+

Overview

The RMK-3-212+ is a surface-mount RF frequency multiplier manufactured by Mini-Circuits. It provides a multiplication factor of three, converting input frequencies in the range of 400 MHz to 700 MHz into output frequencies between 1200 MHz and 2100 MHz. The device operates within a temperature range of -40°C to +85°C and utilizes a compact non-standard SMT package measuring approximately 0.25 x 0.31 x 0.16 inches.

Feature Summary

• Provides a fixed multiplication factor of three for frequency conversion
• Designed for general-purpose up/down conversion applications
• Utilizes a compact surface-mount footprint to conserve PCB space

Applications

• Frequency doubling in wireless communication systems
• Cellular network infrastructure components
• Wi-Fi system signal conditioning
• Bluetooth module integration

Procurement Notes

Verify the specific datasheet version for the RMK-3-212+ to confirm exact electrical parameters and mechanical dimensions. Ensure compatibility with your PCB layout requirements regarding the non-standard SMT package size. Cross-reference the input frequency range (400-700 MHz) with your system design to ensure proper operation within the specified 1200-2100 MHz output band.

Selection Notes

Select this component when a precise triple frequency multiplication is required within the 1.2 GHz to 2.1 GHz output spectrum. It is suitable for designs prioritizing small form factors due to its minimal physical dimensions. Consider the operating temperature range and surface-mount mounting style during circuit board integration planning.

Part Context

This component belongs to the RMK series of RF multipliers from Mini-Circuits, designed for signal conditioning tasks. The series includes variants such as the RMK-3-31+ for lower frequency ranges. These devices are engineered for reliability in wireless communication environments, offering consistent performance across industrial temperature ranges.

Replacement Considerations

Direct substitutes should be sought within the Mini-Circuits RMK series or comparable RF multiplier families. Verify that any replacement maintains the 3x multiplication factor and supports the 400-700 MHz input / 1200-2100 MHz output frequency bands. Check for pinout and package dimension compatibility before implementation.
