BERKELEY, Calif. – Ultraview Corp. in Berkeley, Calif., is introducing the Ultracomb-8G microwave comb generator with high output power levels, low jitter, and spectral content programmability for antenna range testing, communications, and electronic warfare (EW) jamming.
Based on a custom ultra-high-repetition-rate gallium nitride (GaN) differential pulser IC, the palm-sized Ultracomb-8G receives power from a USB 3.0 or 3.1 port through which the user can program comb amplitude, comb picket spacing, and low/high-frequency spectral weighting.
Comb picket spacing can be software-programmed from 10 MHz to 2 GHz in single-ended-output mode in 0.01 Hz steps, generated by an on-board LMX2594 synthesizer driven from an internal 150fs-jitter reference clock or external 10-to-500 MHz reference.
Users of the RF and microwave comb also can program the unit in 1:1 clock mode, enabling the pulse repetition rate of the comb generator to be the same as the external reference and clock input. Its differential outputs enable antenna connections without the use of a BALUN, and 3 decibels higher total output level.
The Ultracomb-8G can create strings of pulses with widths varying from 100 to 800ps, enabling it to generate relatively flat combs with usable energy to 10 GHz or, alternatively, combs with much higher power, but with most of the energy concentrated below 2 GHz.
This is useful in antenna testing for low-frequency antennas over long ranges or in transmitting through lossy media, while retaining the ability to test over a wide bandwidth when using shorter ranges.
