| QHDZ-2Z-1.9G QUAD HYBRID REV: 003, 03/21/06 TECHNICAL DESCRIPTION MULTI-MIX PICO ZAPPER(R) Z-SERIES QUAD HYBRIDS * * * * * * 1.7 - 2.0 GHz HIGH POWER...25 WATTS CW LOW LOSS LOW VSWR SURFACE MOUNT TAPE & REEL RoHS Compliant The Multi-Mix(R) QHDZ-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 QHDZ-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.
