The Linx Technologies TXM-315-LR is a
315 MHz transmitter module from the LR Series, designed for long-range, low-cost wireless data transfer. It is often paired with the RXM-315-LR receiver to form a wireless link capable of distances exceeding 3,000 feet.
Key Specifications (LR Series)
• Frequency: 315 MHz
• Operating Voltage: 2.7V to 5.2V DC
• Output Power: +4 dBm (typical)
• Data Rate: Up to 10 kbps
• Modulation: ASK/OOK (Amplitude Shift Keying / On-Off Keying)
• Package: 8-pin SMD castellation
Core Features and Operation
• Long Range: The LR series uses a synthesized superhet architecture, enabling range capabilities significantly higher than previous, simpler modules.
• Low Current: Designed for power-sensitive applications, with a low-current power-down mode.
• Simple Interface: The module requires no external RF components, except for a 315 MHz antenna.
Pin Assignments
The 8-pin package typically includes the following functionalities:
1. ANT: 50 Ωcap omega antenna connection.
2. GND: Ground.
3. VCC: Power Supply.
4. DATA: Data Input.
5. PDN: Power Down (connect to VCC for normal operation).
6. LADJ: Output Power Adjustment.
