Aeroflex Control Components’ digitally controlled Phase Shifters vary the phase of a Microwave signal in responce to a TTL compatible logic input signal . The unit Consists of an analog phase shifter, series PQ, plus a digital to analog converter. A balanced Strip line configuration keeps the VSWR and amplitude change to a minimum for all values of phase. Standard units operate with 8 BITS allowing 256 discrete values of phase. if 10 BITS are required add -10 to the model number (e.g., QQ-34-10) if 12 BITS are required add -12 to the model number (e.g., QQ-34-12)

 

Features:

  • - 8 bit Digital logic standard
  • - Octave bands up to 18GHz
  • - RF power operation 10mW peak/CW, RF power survival 100mW peak/CW
  • - Custom configurations available

Notes:

  1. The voltages required are ±15V @ 50mA.
  2. Switching speed on all models is 200nS.
  3. Monotonicity is Guaranteed.
  4. The Phase shift varies with frequency at any voltage setting. This variation, referenced to 0° at logic 0 for each frequency, is approximately ±15% for octave models, 10% for models with 25% bandwidth, and ±7.5% for models with 10% bandwidth. Phase flatness of the QQ-65 & QQ-74 is ±25%.
  5. Least Significant BIT = Total Phase Shift divided by the number of steps. 8 BITS = 256 steps.
