OL2300NHN/F,118

RF Transmitter Overview

The OL2300NHN/F,118 is a UHF ASK/FSK fractional-N transmitter manufactured by NXP USA Inc. It features a fully integrated fractional-N Phase-Locked Loop (PLL) frequency synthesizer and an integrated Voltage-Controlled Oscillator (VCO) without external components. The device includes a power amplifier designed to drive an external antenna. It supports operation in the 315MHz, 433MHz, 868MHz, and 915MHz frequency bands with an output power of 12dBm. The component is housed in a 16-VFQFN Exposed Pad surface-mount package.

RF Transmitter Feature Summary

• Fractional-N PLL-based architecture for precise frequency synthesis
• Fully integrated VCO eliminating need for external resonant components
• Integrated power amplifier capable of driving external antennas
• Supports ASK and FSK modulation schemes

RF Transmitter Applications

• Automotive passive keyless entry systems
• Remote keyless entry applications
• Telemetry data transmission
• Sub-1 GHz ISM/SRD band communication links

RF Transmitter Procurement Notes

Verify the complete part number including the suffix /F,118 to ensure correct reel packaging configuration. Confirm that the application design accommodates the requirement for an external antenna, as the internal PA is optimized for this topology. Check RoHS compliance status against current manufacturing revisions. Ensure ESD protection measures are implemented during handling due to the exposed pad thermal interface.

RF Transmitter Selection Notes

Select this component when a compact solution for sub-1 GHz transmission is required without external synthesizer components. It is suitable for battery-operated devices due to independent power-down modes. Consider the 16-VFQFN package constraints for PCB layout. Verify that the target market frequencies (315/433/868/915 MHz) align with regional regulatory requirements for the intended deployment.

RF Transmitter Part Context

The OL2300 series represents NXP's fractional-N PLL transmitter family designed for low-cost, high-performance RF links. This specific variant integrates the synthesizer and PA into a single small footprint. It complements other automotive access solutions like the NCF29AG by providing the transmission stage for immobilizer and entry signals.
