Frequency Multipliers up to 3 THz

Insight Product Company offers a newly developed product line of SL technology multipliers that extend terahertz and millimeter wave sources and synthesizer up to 3 THz.

From 1.5 THz to 3 THz, this novel SL technology delivers consistent output power whereas Schottky diodes based multipliers output power decreases exponentially and offers about 10 times less power at 1.5 THz.

Insight FS extensions provides several options for frequency and amplitude modulation (analog FM/AM modulation, frequency manipulation, pulses modulation).  Insight FS extensions are compact in size and controlled by IEEE, analog input, or manually.

Typical applications:

Imaging, Spectroscopy, terahertz (thz) wave network analyers, heterodyne receivers, terahertz (thz) experiments and research.

-Relatively high output power
-Extremely stable frequency
-Extremely wide tunability
-Extensive possibility of frequency and amplitude modulation and manipulation,
-Convenient for heterodyne and direct detection receiver systems
-Ease of control and operation via IEEE bus
-High reliability


Frequency stability:
5*10-8 or 5*10-11 with microwave signal generator

Control and Programming:
A. Manually by keyboard on front panel
B. Remotely by computer through GPIB

Modulation & Manipulation:
A. Extremely fast frequency modulation by external analog voltage.
B. Frequency manipulation (jumps) by TTL Logic signal.
C. Amplitude ON/ OFF modulation by TTL Logic signal.
