Bias-T (BT-01)

  • max applied voltage: 1-2 kV
  • leakage: <500 nA @ 1 kV
  • frequency range: lower end <100 kHz; hi end >2000 mHz
  • input/output impedance: ~50 ohm / ~50 ohm
  • Manuals and specs
  • Connections:
    • DC: bias input (from power supply)
    • RF: signal output (to amplifier)
    • DC+RF: bias output + signal input, to diode

Notes:

  • in case of a structure with a bias ring and signals/strips being read out, one needs a different connection scheme. Using the mount bought from DESY, one should not use the bias T; instead, one should send directly the bias to from the power supply to the bias ring, and the RF signal from the strip/pixel to the amplifier.
  • using longer cable prevents (i.e. moves out of the region of interest) distortion of the measured pulse due to reflection

Amplifier (AM-01 A)

  • bias voltage: 6-15 V. Gain almost constant above 12V. At 6V gain is about 0.15 of the gain at or above 12V
  • amplification: 53dB (there exists another model with an amplification of 35dB but we don't have it)
  • frequency range: 0.01 - 2000 MHz
  • input/output impedance: ~50 ohm / ~50 ohm

PCB



Required equipment

Chiller

  • should be USB controllable
  • -40C ... ~+40C
  • Julabo XXX
