Overview

The LMT2 transmitter and LMR2 receiver modules offer a multi channel, low power, and reliable data link. This makes the LMT2/LMR2 pair ideally suited to those low power applications where existing wideband modules have insufficient range, or where low cost multi-channel operation is needed without compromising on RF specification or regulatory requirement

Features

• Conforms to EN 300 220-3 and EN 301 489-3 
• High performance double superhet. PLL synthesizer with TCXO 
• quasi-dc (peak sampling) data recovery circuit (for enhanced performance on unbalanced datastreams) 
• SAW front-end filter 
• Data rates up to 5 kbps for standard module 
• Usable range over 1km 
• Fully screened. Low profile 
• Feature-rich interface (RSSI, analogue and digital baseband) 
• Re-programmable via RS232 interface 
• Low power requirements
