MOD153 TRANSCEIVER
2
DESCRIPTION
The MOD153 is a direct
sequence spread spectrum
transceiver module designed to
free use in the 2.4 GHz ISM
band.
The MOD153 transceiver is only
integrated into Kar-Tech remote
control products by Kar-Tech, at
Kar-Tech. There are no user
serviceable parts on the
MOD153 transceiver.
The MOD153 is not designed for
multiple antenna applications
and should not be used to
transmit simultaneously with
any other transmitter.
OPERATION
The MOD153 is a radio
transceiver module for the 2.4
GHz ISM bands. The transceiver
microcontroller includes a CPU,
GPI/O, a fully integrated
frequency synthesizer, a power
amplifier, a modulator and a
receiver unit. The MOD153
microcontroller serial port is
connected to the host via
protection circuits. The data is
sent through a serial port to RF
processor and then to RF circuit
to the antenna and the data
received from antenna is sent to
the serial port and to the host.
The microcontroller is
responsible for the control of the
entire communication. The
MOD153 transceiver contains a
DC regulator which generates a
constant 1.8 VDC for the digital
circuitry. The RF section runs on
the 3.3V supply.
The MOD153 is Direct Sequence
Spread Spectrum that can use
one of 16 channels, where
Channel 1 is 2.405GHZ and
Channel 16 is 2.480 GHZ.
