The QHF-2A series of Quadrature Hybrids covers 1 MHz to 1000 MHz using special lumped element circuits to minimize parts count and size for applications requiring an ultra-miniature package. High performance is achieved in the 0.385" by 0.5" flatpack housing that is ideally suited to aerospace applications where inherent package reliability and hermeticity are essential. VSWR, Max.
