MUTLI-MIX® F SERIES IN-LINE COUPLERS

isolation, and high power handling in a small outline. The ILC series are composed of serial connected

multi-couplers with each coupler having a different nominal coupling value. Equal split loss is maintained

at all of the coupled ports, since the direct-path loss of previous couplers is added. Each of the paths

through a divider / combiner pair have equal insertion phase, but the individual port paths do not.

Accurate phase and amplitude balance make them ideal for applications involving power amplifiers,

signal distribution and processing.

ILC-F in-line 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 ILC-F 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:

•

Cost effective for commercial wireless applications

•

Operating temperature range –55°C to +85°C.

•

RELIABILITY

The product family has passed environmental screening including Thermal shock, Burn-in, Acceleration,

Vibration, Mechanical Shock, Moisture Resistance, Resistance to Solder Heat, and Thermal Cycling Life

Test (>1000 cycles).

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 layers 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 suitable for

automated assembly.
