GENERAL DESCRIPTION & FEATURES 

 

General description 

The CDP-RX-07M and CDP-RX-07MP are low power narrow band FSK receiver modules. 

Double super heterodyne receiver with high reception sensitivity provides stable long distance communication. 

Using a TCXO as the reference oscillator circuit of the radio component ensures high frequency stability and 
a wide operating temperature range from –20°C to +65°C.  

The CDP-RX-07M is compatible with the CDP-RX-05M-R in shape and function, and provides equivalent 
performance. 

The RF channel is selectable from four preset frequency channels and set by the solder jumpers on the 
bottom side of the module and with the CDP-RX-07MP, it can also be set through the connector pins.  

Furthermore, with the CDP-RX-07MP, the user can reprogram each channel with a frequency selected from 
67 frequencies in the 434MHz band using a dedicated setting program. For details of the dedicated setting 
program and how to reprogram the frequency channels, refer to the application note “

How to reprogram the 

preset frequencies of the CDP-TX-07MP/CDP-RX-07MP”

 
 

Features
