OPERATION GUIDE
CDP-RX-02N receiver module
The CDP-RX-02N is a UHF receiver for FM-narrow band modulated signals.
The receiver design is based on the double superheterodyne principle with PLL synthesize
system and micro controller enabling high signal sensitivity, high selectivity, and high
frequency stability not achieved by simple SAW resonator receivers or other low cost designs.
Extensive filtering by an integrated unique SAW filter element enables operation in hazardous
areas where interference may be expected. Steadily increasing use of the available
frequency spectrum demands the application of narrow band systems for maximum operation
reliability and consideration for other users of the ISM band.
The CDP-RX-02N receiver module is designed to match the CDP-TX-02N transmitter module,
though signals from other FM-narrow band transmitters can be received as well.
The CDP-RX-02N is designed for mounting on a PCB. A simple wire can be soldered to the
antenna input or the antenna can be printed on the PC board. Better performance is attained
with commercial antennas for the 433 MHz (458MHz) ISM band.
The receiver modules have two different outputs and an RSSI field power output which
indicates the power of the incoming RF signal.
The AF output is the analog output from the FM detector circuit. Voltage level, DC-offset and
AF noise depend directly on the receiver-input signal. This output can be connected to an
MSK decoder circuit if a transmitter with an additional MSK encoder is used*1. For simple
FSK modulation of digital data, the DATA OUT terminal can be used. It contains a band-pass
filter and comparator with digital output (open collector).
To achieve high signal sensitivity and a short receiver response time no internal muting is
applied. Valid data signals can be detected by utilizing the RSSI output.
*1 The data input of the CDP-TX-02N is for digital signals. If the output of the MSK encoder is input in
DATA IN of the CDP-TX-02N, please make sure to input a digitalized signal in DATA IN by saturating
the signal beforehand.
