RF Subsystem
The R2000 subsystem (aka “RF Circuitry”) is defined as the ARM M4 (aka
Microcontroller), R2000/RFID transceiver (aka “Indy Reader Chip”), power amplifier,
directional coupler, 4-port antenna switch and associated matching components. The
Sensors uses an internal dual linear antenna that only requires two of the four ports. The
H1000 brings out all four of the antenna ports to external R-SMA connectors allowing the
System Integrator to use antennas that are not collocated with the H1000reader. Below
is a block diagram of the R2000 Sub-System.
