Octave Band Bi-Directional Couplers
MINI-LINE ™ Series Octave Band Bi-Directional Couplers are built using stripline construction with both single and multi-section designs. They support standard power sampling up to 50 watts CW and are housed in compact coaxial packages. These couplers deliver proven performance and reliability, even in extreme environmental conditions.
The design is compatible with most industry-standard footprints and mounting configurations. Each coupler offers strong directivity along with excellent VSWR performance on both the primary line and coupled ports.
Engineered to meet a wide range of military specifications, these directional couplers undergo rigorous testing. Performance tests may include thermal shock, thermal cycling, temperature-altitude, and vibration assessments. Additionally, all couplers comply with ISO 9001 standards and are qualified under MIL-STD-201F, MIL-Q-9858A, and MIL-STD-45662.
Standard Environmental Conditions:
Operating Temperature: -55 to +85°C
