Antennas RF Applications

• Low-Power Wide-Area Network (LPWA) devices
• Sub-GHz industrial, scientific, and medical (ISM) equipment
• IoT sensors requiring long-range connectivity

Antennas RF Procurement Notes

Verify the specific revision and tape-and-reel quantity against the manufacturer's latest datasheet before ordering. Confirm that the 829 MHz center frequency aligns with regional regulatory requirements for your target market. Ensure PCB layout guidelines for ground plane clearance are strictly followed to maintain the specified VSWR performance.

Antennas RF Selection Notes

Select this model when designing for Sub-GHz frequencies around 829 MHz rather than standard LTE bands. It is suitable for applications prioritizing range over high data throughput. Compare its physical dimensions and mounting style against existing board space constraints. Verify compatibility with the intended RF front-end matching network for optimal efficiency.

Antennas RF Part Context

This component belongs to Abracon's portfolio of passive ceramic antennas. It serves as a specialized alternative to larger external antennas in space-constrained designs. The product line focuses on enabling connectivity for emerging IoT standards that operate below 1 GHz.

Antennas RF Replacement Considerations

Check for direct substitutes within the Abracon ACAR series that match the 829 MHz frequency and SMD footprint. Ensure any replacement maintains the same 50-ohm impedance and linear polarization characteristics to avoid redesigning the RF circuit.
