15.212 (a) (1) (ii)
REQUIREMENT:
“The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to
ensure that the module will comply with part 15 requirements under conditions of excessive data rates or
over-modulation.”
IMPLEMENTATION:
The 2111 Tag circuitry transmitter drive from the microcontroller is a logic gate providing a fixed drive
that will not overdrive the burst mode oscillator transmitter. The data rate to the transmitter is fixed from the
microcontroller by software and the crystal time base. The modulation is set by the microcontroller and
transmitter as simple on/off keying. The transmitter generates a UWB burst pulse whenever the
microcontroller clocks a logic high ON pulse to the transmitter input.
15.212 (a) (1) (iii)
REQUIREMENT:
Power supply regulation of the modular transmitter:
IMPLEMENTATION:
See (b), limited modular approval
15.212 (a) (1) (iv)
REQUIREMENT:
“The antenna must either be permanently attached or employ a ‘unique’ antenna coupler (at all
connections between the module and the antenna, including the cable)”.
IMPLEMENTATION:
The antenna on the 2111 Module is part of the PWB layout hence will be permanently attached to the
transmitter.
