The QHD-2N-0.56G series is a member of the Multi-Mix QHD family of 3-dB 90° couplers for use in the
450 - 700 MHz range. The QHD-2N-0.56G exhibits low insertion loss, low VSWR, and high isolation.
Excellent phase and amplitude balance and high RF power handling capability make this series ideal for
use in radios for Homeland Security.
The construction of QHD quad hybrids is based on fusion bonded multilayer stripline structures. The
fusion bonding process yields homogeneous monolithic dielectric structures with reliability, ruggedness,
and electrical and thermal performance that are superior to conventional adhesive bonding techniques.
