RF transmitter and receiver modules

View 

These RF Products are ideal for short-range wireless remote control applications where cost is a primary concern. These modules require no external RF components except for the antenna. They generate virtually no emissions, making FCC and ETSI approvals easy.

Mechanical Dimensions and Pin Description

The receiver WZ-R434 and WZ-R418 has a sensitivity of 3uV. Operating voltage is from 4.5 to 5.5 volts-DC, and has both linear and digital outputs. For maximum range, we recommend antenna length to be 1/4 wave of the frequency, That means, for 433.92Mhz, the antenna length is approximately 17cm long . The typical sensitivity is -103dbm and the typical current consumption is 3.5mA for 5V operation voltage.

Low Cost RCT-433 Surface Mount SAW-Stabilized OOK Wireless Remote Control Transmitter
 
Applications
  • Remote Keyless Entry
  • Lighting Controls
  • Wireless Security Systems
  • RFID
 
WZ-433AS series RF transmitter modules offer a cost effective, high-performance solution for remote control type applications. The transmitters are very small (.25" x .4"), have a wide operating voltage range (2-12V), and can deliver 0dBm output power into a 50 ohm load at 3V. SAW-stabilized design guarantees that the center frequency is accurate to 40kHz (@3V), making it suitable for use with any ASK/OOK receiver available.
 
 

Low Cost RCT-433 Super-Regen ASK/OOK Remote Control Receiver

The WZ-433RP series RF receiver modules offer an extremely low cost solution for remote control type applications. The receivers are compatible with almost any ASK or OOK data transmitter and can receive legally transmitted signals from distances as far away as 300 feet. The receivers operate at 5V and draw only 4.5mA.
