Note: “Tc(A3)” denotes the signal cycle at the “A3OP” terminal and the above values are based on the
condition that a bit data group composed of sixteen consecutive signal waves belonging to the same
frequency band (sent from a remote TIRIS transponder in normal operating conditions) has been
previously input; otherwise, the values shown in the table below shall apply.

10 Applied Circuit Configuration – Example
Shown below is an example of applied circuit configuration for constructing a TIRIS Transmit-Receive
RF-module using the RI-RFM-006A. This example illustrates a simplified amplifier circuit for received
signals by eliminating a frequency band rejection filter which effectively eliminates external noises and
signals out of the frequency band of the response signals from the remote TIRIS transponder. In this
configuration, therefore, it is assumed that the available data communication distance of the system could
be easily affected by environmental conditions.
Note that this is only one of various possible applications. For more information of applied circuit
configurations, refer to the Application Handbook issued by our TIRIS Operation Dept.
