INTRODUCTION
The TS4000 is a high-speed radio modem that consists of a modem board, radio transceiver
board and metal enclosure. The radio transceiver board connects to the modem board with a
flexible printed circuit.
board and metal enclosure. The radio transceiver board connects to the modem board with a
flexible printed circuit.
Radio Transceiver Board
The radio transceiver board for this application is an E.F. Johnson DL3422. This device is being
used without any modifications. The DL3422 has received FCC type acceptance with an FCC ID
of ATH2423422-007. All circuit descriptions and details for the radio transceiver can be found in
the type acceptance document for the DL3422. A copy of this has been included with this
application. The radio transceiver is available in a frequency range from 132-174 MHz and
includes a temperature stable reference oscillator with a frequency stability of ± 2.5 PPM.

Modem Board
The modem board provides the serial data interfaces that the user’s equipment interfaces to. The
modem board also controls the operation of the radio transceiver. This control includes
controlling the radio power and frequency and also controlling the modulation, data rate and
frequency deviation of the transmit signal. Note that it is this transmit signal that defines the
emission bandwidth and spectral efficiency.

Radio Flex Circuit
A flex circuit is used to interconnect the radio transceiver board to the modem board. This flex
circuit is also used to interconnect the serial port 2 connector to the modem board. The J11
interconnecting diagram included with the modem board schematic provides the specific
connections provided by the flex circuit for connecting the radio transceiver to the modem board.
