DE6003
DIGITAL RADIO TRANSCEIVER
(Supersedes DS3506-6.3, September 1994)
DS3506-7.3
The DE6003 is a high performance frequency hopping
microwave radio, designed for spread spectrum operation. It oper-
ates in the 2·4 to 2·5GHz band. Portions of this band are available
for data transmission on an unlicensed basis in most countries on a
shared basis with existing users (that include microwave ovens,
intruder alarms etc).
The radio is highly resistant to interference and has many other
design features that ensure the most reliable data
www.DataShteraent4sUfe.cropmossible (when used in conjunction with an advanced
protocol).
Co-location with other simultaneous users (as well as interfer-
ers) is possible, giving an unsurpassed data density in a given area.
The radio has been designed specifically for portable
computer applications (including use ‘on the move’). It is also suit-
able for a wide variety of other applications including
inventory control, point of sale terminals (including handheld) and
data logging.

Environmental Limiting Conditions of Use
q Operational Temperature: 0°C to 155°C.
q Storage Temperature 220°C to 170°C.
q Humidity: 95% non-condensing.
q ESD: Human body model, 4000V.
q Vibration Testing: 10 t0 2000Hz, displacement 61mm,
acceleration 2G.
Operating temperature
When in operation the transmitter power amplifier (PA)
dissipates the highest amount of power and creates the highest
temperature. In order to keep the temperatures to a safe level
the environment in which the radio is operated must be kept
within the values specified in Environmental Limiting Conditions
of Use, above.
The radio dissipates this heat from the whole of its surface,
www.DataShienept4aUrt.iccoumlar from the metallic screen; steps must be taken to
prevent overheating as early failure of the radio may occur.
Depending on the air temperature surrounding the radio, the
PA duty cycle must be set to keep the dissipation to a safe value.
The transmitter power amplifier derating curve of Fig.2 shows
the derating factors that should be applied in order not to
exceed the maximum working temperature. Running at the
maximum permitted temperature on the PA will (as with all
semiconductor devices) result in shorter operational life than
DE6003
running at lower temperatures. The thermal time constant of
the radio is 1 minute and this derating curve can only be applied
to transmitter for continuous transmit times of less than
20 seconds; above this time the duty cycle should be
considered 100%. For continuous operation the case
temperature should not exceed 40°C.

TIMING SPECIFICATIONS AND CONDITIONS OF USE
The timing diagrams, Figs. 3 to 8, show some of the normal sequences used in the control of the DE6003 and are used to illustrate
timing relationships. Table 6 is the truth table for these signals values for which are given in Table 7. Each entry in Table 7 is described
on pages 9 and 10.
