MOD164 TRANSCEIVER
DESCRIPTION
The MOD164 is a frequency
hopping spread spectrum
transceiver module designed to
be compatible with US (FCC Part
15.247) and Canadian (RSS-
210) regulations for license free
use in the 900 MHz ISM band.
The MOD164 is designed for
mobile applications in
accordance to Part 2.1091(b).
OPERATION
The MOD164 is a radio
transceiver module for the 900
MHz 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 MOD164
microcontroller serial port is
connected to the host via
The MOD164 transceiver is only
integrated into Kar-Tech remote
control products by Kar-Tech, at
Kar-Tech. There are no user
serviceable parts on the
MOD164 transceiver.
The MOD164 is not designed for
multiple antenna applications
and should not be used to
transmit simultaneously with
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
MOD164 transceiver contains a
DC regulator which generates a
constant 1.8 VDC for the digital
any other transmitter.
circuitry. The RF section runs on
the 3.3V supply.

MOD164 TRANSCEIVER
The MOD164 hops on 50 channel
frequencies that are selected in
a pseudo random order. An
example of the order is:
{48, 25, 17, 20, 41, 37, 36,
10, 15, 44, 30, 6, 42, 33,
5, 8, 28, 1, 23, 49, 16,
3, 19, 29, 21, 43, 31, 9,
18, 27, 22, 45, 13, 2, 32,
11, 14, 46, 12, 24, 4, 7,
38, 47, 35, 40, 50, 34, 39,
26}
where Channel 1 is 902.5 MHZ
and Channel 50 is 927.00 MHZ.
The dwell time of the hopping is
350ms. Each channel is used
equally on average.
The receivers are matched to
the transmitters to use the same
hopping channel sequence and
they hop channels in
synchronization with the
transmitter’s signals.
