Alcatel 101200429000 Power Divider – 746‑776 MHz with Heatsinks

The Alcatel 101200429000 is a high‑performance RF power divider designed for the 746‑776 MHz frequency band, commonly used in cellular, broadcast, and public safety communication systems. This in‑phase, equal‑power splitter features integrated heatsinks to ensure stable operation even under high‑power conditions, making it ideal for base station combiner/distribution networks and distributed antenna systems (DAS).

Product Description

This power divider provides a simple and reliable way to split an RF input signal into two or more outputs with minimal amplitude and phase imbalance. The 101200429000 model is a 2‑way or 4‑way Wilkinson‑type divider (depending on configuration) that offers low insertion loss (typically < 0.5 dB) and high port‑to‑port isolation (> 20 dB) across the 746‑776 MHz band. The inclusion of integrated heatsinks allows the unit to dissipate heat generated by high‑power RF signals, maintaining performance and longevity.

Constructed with precision machined aluminium housing and high‑quality RF connectors (Type N or 4.3‑10), the divider is weatherproof and suitable for both indoor and outdoor deployments. It is fully passive, requiring no external power, and is designed for 50‑ohm systems.

Deployment Scenarios

This power divider is commonly used in cellular base station feeder networks to distribute RF signals from the transmitter to multiple antennas. It is also found in DAS head‑end equipment to split signals for different coverage zones. In broadcast transmission, it feeds multiple antennas from a single transmitter for redundancy or pattern shaping. The 746‑776 MHz band includes the 700 MHz public safety and LTE bands (e.g., Band 14 in the US), making this divider relevant for critical communications infrastructure.

With its high power handling and robust thermal design, the 101200429000 is suitable for both macro site and small cell deployments.

Installation and Maintenance

Installation involves mounting the divider to a stable structure using the provided brackets. The heatsinks require sufficient airflow for optimal cooling. RF connections should be torqued to specified values. The divider is maintenance‑free, and its passive design ensures reliable operation for many years.

Compliance

Meets ETSI EN 300 019 environmental standards and is RoHS compliant.

Conclusion

The Alcatel 101200429000 power divider offers a reliable, high‑performance solution for RF splitting in the 746‑776 MHz band. Its combination of low loss, high isolation, and effective thermal management makes it an essential component for modern wireless distribution networks.
