Analog Diode Phase Shifters
An Analog Phase Shifter Continuously Changes the phase of a microwave signal by varying a DC voltage. Since the DC voltage applied to the diode is reverse bias, the current drain is negligible (typically less than 10uA). A Balanced stripline configuration keeps the VSWR and amplitude ripple to a minimum for all values of phase.
Features:
- Octave bands up to 18GHz
- Fast Phase responce as low as 10nS
- RF power operation 10mW peak/CW, RF power survival 100mW peak/CW
- Bias connection using pin or connector options
- Custom configurations available

| Notes: |
- Monotonicity is Guaranteed.
- 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%.
- A Connector, (SMA Female) is available in place of the bias pin at no extra charge. This will be placed at the center
of the surface marked "H" on the drawing. This is the .38 x "A" surface. If a SMA Female is desired, add the suffix
"C" to the model number (e.g., PQ-45C)
- Linearization models available, call for outline and details.
