Abstract
This paper presents a 2 GHz pulse generator in balanced configuration for ground penetrating radar(GPR). In order to improve the input and output matching, the pulse generator is designed in balanced configuration with $90^{\circ}$ hybrid couplers. The designed pulse generator was fabricated using PCB process. The fabricated pulse generator draws 1 mA current from a 5 V power supply with 27.6 % efficiency. The measured output voltage swing is $3.7V_{pp}$ at 100 MHz pulse repetition frequency(PRF). The pulse width is 2 ns and the input and output return loss is more than 10 dB at the operating frequency of 1.7~2.6 GHz.
