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.
