General Notes:
1. PTM-64A series phase shifters are controlled directly
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
NOTES: 1. Tolerance on 3 place decimals ± .020(.51) except as noted.
2. Dimensions in inches over millimeters.
