 DEL-RX300-930MHz

 

The DEL-RX300-930MHz is a multi-channel, single RF receiver board, designed for applications within the 300 to 930MHz range. The module is developed for universal applications in the European ISM bands 433 and 868MHz and for similar applications in North America and Asia, e.g. for 315MHz and 915MHz.
The sole significant modification of external parts affects the quartz for systems requiring different application frequencies.
Based on a receiver IC with a “Double-Conversion Super-Heterodyne” architecture, the board includes furthermore a complete integrated FSK- and ASK-demodulator.
The utilized IC allows the employment of an external IF-filter for the familiar 10,7MHz frequency with bandwidths for NB (narrow band) and WB (wide band). In this manner the receiver can be adjusted for both NB and WB applications.
One of the eminent characteristics of the DEL-RX300-930MHz board are the two RF-inputs. This allows applications such as “Antenna-Diversity” or “LNA-Cascading” to be easily realized.
The board runs with a supply voltage of 2.1 to 5.5V with a typical current consumption of 6.5 to 8.1mA.
