Pulse Technology Products

Model No. XPR

1.Pulse Filter

  Microwave Coaxial Type Gaussian Filter [FLT03]   Low-Pass and Rise Time Filters (Pulse Filters) [FLT10]

A filter that generates neither overshoot nor undershoot when impulses are passing through it. It optimizes the S/N ratio.


A filter that slows down the rise and fall times of pulses.The impedance is matched even at out-of-band frequencies to prevent overshooting and other problems.


2.Pulse Amplifier

  Pulse Anplifier [amp02]    

High amplification pulse amplifier suitable for pulses of 1nsec width.



3. Pulse Generator(Oscillator)

  110~140GHz Pulse Oscillator System [PAH01]  

A Millimeter wave oscillator with oscillating frequency mechanically selectable between 110 GHz to 140 GHz. Equipped with variable attenuator. You can check output by a power meter.


4. Bias Tee

  Bias-TEE(Room temperature/Low temperature)  [BYT01]   Bias-TEE For Large Current [BYT05] 

KEYCOM’s Bias-TEE devices are effective in low frequency ranges as well as high frequency ranges, with resistance in DC supply lines.
Cryogenic types are also available.


Bias Tee for large current,with maximum supply DC current of 15A and 30A.


5. DC Blocks

  Millimeter-wave, DC Blocks [DCC01]    

This type has inner conductor for DC blocking.
It is used for millimeter waves, and a type of passing through low frequencies is optimal for ultra high-speed pulses.


6. Wideband Antenna

  Double Ridge Horn Antenna  [ANT14]   Fermi Antenna [ANT88] 

A double ridge waveguide is used for the power feed, which allows for wide bandwidth use.


Printed antennas with fractional bandwidth of over 100%, suitable for UWB applications.

7. Pulse Radar

  76GHz Standard Radar (Pulse Radar)  [PAR02]   Pulse Doppler Radar [PAR73] 

A double ridge waveguide is used for the power feed, which allows for wide bandwidth use.


Possible to display received waves in quasi-real time
Received signals can be imported into a PC in CSV format for detailed data analysis.


  24 GHz Edge Radar (Pulse Radar)  [PAR01]   94GHz Pulse-Type High-Sensitivity Weather Radar [RAD75]

This radar performs highly precise distance measurement in the range between 50cm and 35m.


Millimeter-wave (94 GHz band) weather radar for observing fog, smoke, and other phenomena that are difficult to observe using optical method. This is used for verification of EarthCARE (Earth Clouds, Aerosols and Radiation Explorer) satellite onboard cloud radar .
