Phase Tolerance: 90 3 max. Amplitude Balance: 1 dB max. VSWR (In/Out): < 300 MHz: 1.3:1 max. > 300 MHz: 1.5:1 max. CW Input: 1 W max. Weight, nominal: 0.1 oz (2.8 g) For complete Model Number replace *** with desired Center Frequency in MHz. A-Package Outline Typical QHF-23A-60 Performance NOTES: 1. Tolerance on 3 place decimals .010(.25) except as noted. 2. Dimensions in inches over millimeters. 3. Lead dimensions apply only at body. 4. All unmarked pins are case ground. 20Feb96 General Notes: 1. The QHF-23A series of 3 dB Quadrature Hybrids covers 1 to 1250 MHz using special lumped element designs to minimize size for high performance in applications requiring small size. The 0.385" by 0.5" flatpack which houses these 3 dB Quadrature Hybrids is ideally suited to aerospace applications where inherent package reliability and hermeticity are essential.
