1. The PQF-2E-500 is a 90° Power Divider/
Combiner covering 30 MHz to 1 GHz using
wideband 45° lead-lag circuits to generate the
quadrature phase relationship between the
outputs. This approach provides substantially
better bandwidth than the conventional
narrowband approach of using calibrated line
lengths to generate the required phase
relationships.
2. The design approach used in the
PQF-2E-500 makes it suitable for applications
requiring extremely broad bandwidth as a
logical tradeoff for its increased complexity,
insertion loss and size.
3. The PQF-2E-500 uses a low profile, space
saving flatpack. It may also be supplied in the
equivalent R-size Meri-Pac
™
, E-size Surface
mount or connectorized package.
NOTES:
1. Tolerance on 3 place decimals
±
.010(.25) except as noted.
2. Dimensions in inches over millimeters.
3. Dimensions marked with * apply only at body.
4. All unmarked pins are case ground.
