Claim:
1. A pulse position modulation scheme impulse radio transmitter comprising: a bipolar return-to-zero type short-pulse generator; a bandpass filter that has a predetermined pass frequency band and which allows an output of the bipolar return-to-zero type short-pulse generator to pass; a transmission amplifier that amplifies an output of the bandpass filter; and a transmission antenna, wherein the bipolar return-to-zero type short-pulse generator includes: the trigger flip-flop with a position modulation function has a master-slave circuit, and a slave unit of the master-slave circuit includes a first inverter, a second inverter, and a variable delay circuit the delay amount of which is selected by a signal from a selector unit, wherein an input terminal of the first inverter is connected to an output terminal of the second inverter, an input terminal of the variable delay circuit is connected to an output terminal of the first inverter, and an input terminal of the second inverter is connected to an output terminal of the variable delay circuit.
