GENERAL SPECIFICATIONS
Coupling: Impedance: Isolation: -- 3 dB nom. 50 nom. 20 dB min., 25 dB typ.
1- 300 MHz 15% of fo For complete model number replace *** with desired center frequency
General Notes: 1. The QHG-22B series covers 1 to 300 MHz in 30% bandwidth units using a special lumped element design to minimize size and cost. The low 0.175" profile surface-mount package which houses these 3 dB Quadrature Hybrids is ideally suited to terrestrial and aerospace applications alike where hermeticity and inherent package reliability are essential.
Insertion Loss: <75 MHz: 0.5 dB max., 0.3 typ. >75 MHz: 0.75 dB max., 0.5 typ. Phase Tolerance: 90 2 max. Amplitude Balance: 0.5 dB max., 0.25 dB typ. VSWR (In/Out): 1.3:1 max. CW Input: 4 W max. (1.2:1 VSWRout)
