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-PacTM , 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.
