RXD-418-KH

Product Overview

RXD-418-KH from TE Connectivity Linx is a sub-GHz RF receiver/decoder module. This product detail focuses on receiver architecture, supported radio bands, interface requirements and sourcing relevance for engineering and procurement teams.

It is suitable for designs where the exact ordering suffix must be matched for package, firmware option, temperature grade, tape-and-reel format and host interface compatibility before purchase.

Key Features

• Manufacturer: TE Connectivity Linx
• Part Number: RXD-418-KH
• Device Type: sub-GHz RF receiver/decoder module
• Receiver Architecture: Linx KH/RXD receiver decoder module combining RF receiver function with digital decoding for remote-control links
• Frequency Range: 418 MHz
• Modulation / Protocol: OOK/ASK encoded remote-control reception with KH/KH2 decoder output family
• Decoder Function: Integrated address/data decoding reduces host MCU workload in fixed-code remote-control applications
• Receiver Sensitivity: High-sensitivity short-range receiver class for keypad, relay and access-control systems
• Data Output: Decoded logic outputs or serial/parallel control signals depending on KH/KH2 device variant
• Supply Voltage: Low-voltage module operation; verify exact KH/KH2 receiver decoder datasheet before replacement
• Mounting Type: Through-hole or module-style receiver package depending on RXD generation
• Package / Case: RXD receiver decoder module; KH/KH2 suffix defines encoder/decoder compatibility and footprint
• Design Notes: Confirm the matching Linx encoder, operating frequency and address-code format before substituting the receiver decoder module.

Applications

Keyfob receiver boards, garage/gate control, relay control, security panels and simple wireless command links.

Repair and production support for Linx KH-series control systems where RF frequency and decoder compatibility must match.

Quality & Sourcing

Antrex Electronics can support sourcing for RXD-418-KH through available stock checks, BOM consolidation and alternative-lot review. For RF receiver components, packaging condition, date code, MSL handling and original labeling should be checked before shipment.

For project builds, repair support or shortage coverage, Antrex Electronics can coordinate visual inspection, package verification and third-party testing when required. This helps buyers manage risk when sourcing discontinued, legacy or hard-to-find RF receiver parts.
