The Multi-Mix® QHD-Z series provides a 3 dB, quadrature coupler with low insertion loss, high isolation,
and high power handling in a small outline. Accurate phase and amplitude balance make them ideal for
applications involving IQ networks, power amplifiers, signal distribution and processing.
The QHD-Z series is an easy to install SMD designed specifically for the full spectrum of wireless
applications. The high stability ceramic filled PTFE dielectrics utilized in these components are
compatible with common substrates such as FR-4, G-10, and polyamide. The wrap around ground plane
provides excellent EM shielding.
