MIKROE-2351

Antennas RF Overview

The MIKROE-2351 is a passive indoor rubber whip antenna designed for the 433 MHz ISM band. It features a straight mechanical form with vertical polarization and provides a gain of 1.5 dBi. The unit operates at a maximum power rating of 50 W with a 50 ohm impedance. It utilizes an SMA male connector for panel mount installation, extending the range of compatible LoRa and OOK RX Click boards.

Antennas RF Feature Summary

• Straight whip design with vertical polarization
• SMA male connector interface
• Optimized for 433 MHz ISM band operations

Antennas RF Applications

• LoRa communication systems
• OOK receiver modules
• ISM band data transmission devices

Antennas RF Procurement Notes

Verify that the specific SKU matches the straight configuration rather than the right-angle variant (MIKROE-2352). Confirm the SMA male connector type aligns with the host device's port. Ensure the 50 ohm impedance specification meets the system requirements for the intended 433 MHz application.

Antennas RF Selection Notes

Select this model when a linear antenna profile is required for space-constrained or aesthetic installations. It serves as a direct replacement for standard rubber antennas in MikroElektronika Click board ecosystems. Consider the 1.5 dBi gain level against higher-gain alternatives if extended range beyond standard LoRa coverage is necessary.

Antennas RF Part Context

This component belongs to the MikroElektronika accessory line, specifically engineered for the mikroBUS Click platform ecosystem. It complements digital and RF expansion boards by providing reliable wireless connectivity solutions. The product supports various cellular and IoT protocols operating within the UHF frequency range.

Antennas RF Replacement Considerations

MIKROE-2352 is a confirmed substitute offering identical electrical specifications but with a right-angle connector configuration.
