TECHNICAL DESCRIPTION / APPLICATION

MULTI-MIX

The Multi-Mix

directivity. Precise coupling and frequency sensitivity make them ideal for applications power ampli-

fiers, 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 perform-

ance 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 applica-

tions. 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:

• Available on tape and reel

• Cost effective for commercial wireless applications

• Industry standard size

• Temperature stable from –65 to +125 degrees C.

• Can be integrated with other Multi-Mix

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

Multi-Mix

bonded together into a multilayer structure. The fusion bonding process yields a homogeneous mono-

lithic structure with superior performance at microwave and millimeter wave frequencies. The bonded

multilayers can contain embedded semiconductors, MMICs, etched resistors, circuit patterns, and plat-

ed-through vias to form a SMD module that requires no additional packaging and is ready for pick and

place.
