Crane Aerospace & Electronics Low RF Transients / Fast Switching Time / Monotonic Output / BNC or SMA Phase Shifters PTM64A

from TTL logic circuits and are available for center frequencies from 10 to 250 MHz. 2. Their lumped element design is inherently narrow band since it utilizes a quadrature hybrid in each switch section. However, this approach provides much smoother phase transitions than a switched cable design since the switching does not take place in the RF signal path. This feature makes the PTM-64A series preferable for applications where minimizing switching transients is important. 3. Accuracy and temperature stability of each phase shift section allows for a resolution of 5.6°, but as total phase shift increases, overall accuracy deteriorates due to cumulative internal reflections.
