TECHNICAL DESCRIPTION / APPLICATION
MULTI-MIX® DIRECTIONAL COUPLERS
The Multi-Mix® CSD series provides directional couplers with low insertion loss, low VSWR, and high
directivity. Precise coupling and frequency sensitivity make them ideal for applications power amplifiers, signal distribution and processing.
CSD directional couplers are fusion bonded multilayer stripline assemblies. The fusion bonding process
yields a homogeneous monolithic dielectric structure with reliability, ruggedness, and electrical performance that is superior to conventional adhesive bonding techniques.
The CSD 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.
Additional benefits include:

RELIABILITY
All CSD series components are 100% tested. The product family has passed environmental screening
per MIL-STD-202 including Thermal shock, Burn-in, Acceleration, Vibration, Mechanical Shock, Moisture
Resistance, Resistance to Solder Heat, and Thermal Cycling Life Test (1000 cycles).
THE MULTI-MIX® PROCESS
Multi-Mix® is a manufacturing process based on fluoropolymer composite substrates that are fusion
bonded together into a multilayer structure. The fusion bonding process yields a homogeneous monolithic structure with superior performance at microwave and millimeter wave frequencies. The bonded
multilayers can contain embedded semiconductors, MMICs, etched resistors, circuit patterns, and plated-through vias to form a SMD module that requires no additional packaging and is ready for pick and
place.
