SYN470 RF Transmitter Chip
The SYN470 is a single-chip RF (Radio Frequency) transmitter IC manufactured by Synoxo (now part of RFIC Solutions).
Key Features
Frequency Range:
- Operates in the 433MHz ISM band (typically 433.05-434.79MHz)
- Some variants support other sub-GHz frequencies
Modulation:
- ASK (Amplitude Shift Keying)
- OOK (On-Off Keying)
- FSK (Frequency Shift Keying) capabilities
Power Supply:
- Low voltage operation (typically 2.1V to 3.6V)
- Low power consumption for battery-operated devices
Common Applications
- Remote Controls - Garage doors, car alarms, toys
- Wireless Sensors - Temperature, humidity, security sensors
- Home Automation - Light switches, smart home devices
- Industrial Telemetry - Short-range data transmission
Technical Specifications
- Output Power: Typically up to +10dBm
- Data Rate: Usually up to 10kbps
- Package: Small form factor (often SOT-23 or similar)
- Interface: Simple serial data input
Advantages
- Very cost-effective solution
- Simple implementation - minimal external components
- Good for short-range, low-data-rate applications
- Low power consumption extends battery life
The SYN470 is popular in consumer electronics where cost is critical and high-performance RF isn't required. It's often paired with corresponding receiver chips like SYN480 series for complete wireless communication solutions.
