    CDA70 MODEM DESCRIPTION 2. Description of the CDA70 radio modem 2.1. General The CDA70 radio modem is a device for wireless data transmission. Communication between two radio modems is a simplex one and is carried out on a single frequency. Modems work in frequency band of 143 to 174 MHz (CDA70V) and 403 to 470 MHz (CDA70U).

  • Page 6: Modem Component

    CDA70 MODEM DESCRIPTION Modem component 2.3.2. The modem part converts digital bit flow from the microcomputer to the FFSK or GMSK analogue modulation, which is brought to the transmitter of the radio data module. And vice versa, it converts analogue signal from the receiver to digital bit flow to the microcomputer. The modem part is designed on the basis of a CML integrated circuit.
