General Notes:
1. The PSP and PSPM
series
of
panel
mountable
phase
shifters use lumped
element quadrature
hybrids together with
tunable pair of LC
networks to generate
variable phase shifts up
to 180°. An additional
180° of phase shift is
available by activating
the included switch.
2. The continuous
phase shift control is
provided with a lock to
prevent inadvertently
changing the setting.
NOTES:
1. Tolerance on 3 place decimals
±
.020(.51) except as noted.
2. Dimensions in inches over mm.
3. Dial, Drive Knob and Knob Lock
require customer assembly.
4. Dial is uncalibrated, ’0’ dial
reading is min. insertion phase.
3. If continuous 0° to
360° phase shift is
required, Merrimac’s
PS-5 series should be
considered.
