Abstract ---- This paper presents a description of a
new method to generate a short impulse based on
a counter designed on BiCMOS SiGe technology.
This architecture includes a new method to
modify the PRF (pulse repetition frequency) by
changing the counter division ratio and an easy
way to control the impulse frequency center. A
pseudo-noise sequence prescaler modulates the
impulses with specific modulation schemes, such
as pulse position, bi-phase modulation or a
combination of both. The total power
