Overview
The Microlab BK-747E is a dual diplexer designed for the combination and separation of RF signals in public safety applications. It operates with specific frequency bands: PCS band 1850–1995 MHz and AWS-WCS bands 1695–1780 MHz and 2110–2180 MHz. The component supports power levels ranging from 50 to 120W, depending on the specific configuration within the BK-74 series. It features N-Type connectors for standard interfacing.
Feature Summary
- Enables simultaneous combination and separation of signals across PCS and AWS-WCS frequency bands
- Supports high power handling capabilities suitable for base station infrastructure
- Utilizes N-Type connectors for reliable RF connectivity
Applications
- Public safety communication systems
- Base station signal aggregation
- RF multiplexing in outdoor enclosures
Procurement Notes
Verify the exact power rating (50W vs 120W) and connector type against the specific datasheet revision, as the BK-74 series encompasses multiple variants. Confirm that the N-Type interface matches existing cabling infrastructure. Ensure the frequency specifications align precisely with local regulatory requirements for PCS and AWS-WCS bands before procurement.
Selection Notes
Select this model when integrating PCS and AWS-WCS signals into a single transmission path. Consider the BK-747E for applications requiring robust signal isolation between the 1850–1995 MHz range and the lower/higher AWS-WCS bands. Evaluate thermal management requirements given the 50–120W power handling capacity.
Part Context
The BK-747E belongs to the Microlab BK-74 series, a family of diplexers tailored for public safety and broadband wireless access. These components are frequently integrated into outdoor broadband enclosures, such as the Charles Universal SH60-702018, which houses multiple radios and passive RF components to consolidate antenna connections.
Replacement Considerations
The BK-745E is a related dual diplexer within the same series but may differ in specific band configurations or power ratings. Verify compatibility by comparing the exact frequency split points and insertion loss specifications against the BK-747E datasheet.
