RF Transmitters and Receivers with Integrated Encoder and Decoder Chips
The KH2 Series RF modules are ideally suited for OEM applications, such as remote control / command, security, and automation. The transmitter module combines a highly optimized SAW-based RF transmitter with an on-board remote control encoder. The receiver module combines an advanced synthesized RF receiver with an on-board remote control decoder. The transmitter module accepts up to eight parallel inputs, allowing direct connection of switches, contacts, or microprocessor control lines. The receiver module provides eight logic-level outputs for connection of devices under control, such as relays, motors, indicators, or microprocessor lines. Ten tri-state address lines are also provided to allow for security and the creation of 3 (59,049) unique transmitter / receiver relationships. Together, the modules form a reliable wireless connection capable of operation over distances of up to 3,000 feet. The modules are also individually compatible with a complete family of FCC pre-certified OEM products, which include keyfob and handheld transmitters, relay and AC control modules. Housed in compact reflow-compatible SMD packages, the modules require no tuning or external RF components (except an antenna).
