Cryogenics

TTI develops equipment to operate at cryogenic temperatures down to 4K (-269ºC) such as laboratory cryostats and cryogenic Low Noise Amplifiers (LNAs).

Lab cryostats

TTI’s product portfolio includes reconfigurable cryostats. The main characteristics of these cryostats are:

  • Closed cycle operation (need not  be refilled with helium)
  • Internal dewar temperature down to 4K
  • High temperature stability (more than 24 hours)
  • Automatic cycles and remote operation
  • Hermetic customized interfaces DC & RF
  • Servo-controlled power supply
  • Internal wiring and external interconnections
  • Cooling/Heating system (~3 / 2 hours)

Low Noise Amplifiers

Cryogenic Low Noise Amplifiers are based on GaAs, InP HEMT or hybrid technologies. They offer high stability; gain ranges from 33 dB to 39 dB and noise temperatures below 5K @15K. TTI develops S band(2,21 – 2,35 GHz), C band (4-8 GHz) and X band (8,15 – 8,63 GHz) Cryogenic LNAs.

TTI is able to integrate and produce large scientific equipments upon request (based on either specifications or previous design), integrating cryostats, LNAs, Antenna, Reception chains, Control system, Power supply, etc.
