The QHD-2BH-0.45G series is a member of the Multi-Mix QHD family of 3-dB 90° couplers for use in the
380-520 MHz range. The QHD-2BH-0.45G 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 base station power amplifiers in particular and radio transceivers, receiver/antenna multicouplers
and RF signal distribution and processing equipment in general.
The construction of QHD quad hybrids is based on fusion bonded multiplayer 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.
