First Claim
Patent Images
1. An ultra-wideband (UWB) dual burst transmitter, comprising:
- a trigger pulse initiation circuit actuated by a single input trigger pulse;
an initial trigger pulse generator connected to the trigger pulse initiation circuit to generate a first trigger pulse;
a delayed trigger pulse generator connected to the trigger pulse initiation circuit to generate a second trigger pulse at a selected delay from the first trigger pulse;
a bias driver connected to the initial and delayed trigger pulse generators; and
a RF burst oscillator connected to the bias driver and actuated thereby in response to the first and second trigger pulses to generate a pair of RF bursts separated by the selected delay.

Abstract
A dual burst transmitter for ultra-wideband (UWB) communication systems generates a pair of precisely spaced RF bursts from a single trigger event. An input trigger pulse produces two oscillator trigger pulses, an initial pulse and a delayed pulse, in a dual trigger generator. The two oscillator trigger pulses drive a gated RF burst (power output) oscillator. A bias driver circuit gates the RF output oscillator on and off and sets the RF burst packet width. The bias driver also level shifts the drive signal to the level that is required for the RF output device.

20. A method of generating a precisely spaced pair of ultra-wideband (UWB) RF bursts, each starting with the same phase, from a single input trigger pulse, comprising:
-
generating an actuation signal from the input trigger pulse; passing the actuation signal through two trigger pulse generating paths to produce an initial trigger pulse and a delayed trigger pulse separated by a selected delay from the initial trigger pulse; and driving an oscillator with the initial and delayed trigger pulses to produce a spaced pair of RF bursts, the RF bursts being separated by the selected delay. - View Dependent Claims (21, 22, 23, 24)
