RF Receivers datasheet and documents for MICRF218AYQS-TR
RF Receivers Overview
The MICRF218AYQS-TR is a surface-mount AM receiver module operating within the 300MHz to 450MHz frequency range. It features a sensitivity of -108dBm and supports data rates up to 10kbps. The device requires a supply voltage between 3V and 3.6V, drawing 5.5mA during reception. It is housed in a 16-QSOP package with dimensions of 0.154 inches (3.90mm) width. The component operates across a temperature range of -40°C to 85°C.
RF Receivers Feature Summary
- Integrated ASK/AM demodulation for low-speed wireless communication
- Built-in RSSI capability for signal strength monitoring
- Wide intermediate frequency bandwidth for robust signal processing
RF Receivers Applications
- ISM band wireless sensor networks
- Garage door opener systems
- Remote Keyless Entry (RKE) receivers
RF Receivers Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm the manufacturer designation as Microchip Technology, formerly Micrel. Ensure the 16-QSOP package type matches the PCB footprint requirements. Check for any Product Change Notifications regarding assembly sites or material updates before finalizing procurement plans.
RF Receivers Selection Notes
Select this component for applications requiring simple AM modulation at low data rates under 10kbps. It is suitable for battery-powered devices due to its moderate current consumption. Consider the wide IF bandwidth if operating in environments with potential interference. Ensure the design supports the required 3V to 3.6V supply voltage range.
RF Receivers Part Context
This part belongs to the MICRF218 family of RF receivers designed for short-range wireless applications. It serves as a cost-effective solution for industrial and consumer electronics requiring reliable ASK/AM reception. The device integrates necessary front-end components into a compact surface-mount package.
RF Receivers Replacement Considerations
MICRF218AYQS is available in tube packaging instead of tape-and-reel. MICRF219AAYQS-TR offers OOK modulation support with improved sensitivity but may require circuit adjustments.
