Among the many solutions available, the ETL Systems COM02L1P-2502 2-Way L-Band Passive Splitter/Combiner stands out as a cornerstone component — delivering exceptional RF performance and long-term reliability.
At VSATPlus, we are proud to offer this high-quality unit from ETL Systems, one of the world’s most respected manufacturers of RF distribution equipment. In this article, we’ll explore in detail the features, technical performance, applications, and benefits of the COM02L1P-2502, explaining why it has become a preferred choice for network operators and integrators worldwide.
The ETL COM02L1P-2502 is a 2-way passive splitter/combiner designed to handle L-Band frequencies ranging from 850 MHz to 2150 MHz. It enables the efficient splitting or combining of RF signals within satellite ground stations and communication networks, ensuring consistent performance across a wide range of applications.
Built for durability and precision, the COM02L1P-2502 maintains excellent signal integrity, low insertion loss, and superior return loss, even under demanding operational conditions. It is available in multiple impedance and connector configurations, providing flexibility for a wide range of system architectures.
The COM02L1P-2502 operates seamlessly across the full L-Band spectrum, supporting applications from satellite downlinks and uplinks to IF distribution and signal monitoring.
With a typical insertion loss of just 0.4 ± 0.2 dB and isolation values up to 25 dB, the unit ensures that signal degradation and crosstalk are minimized. This makes it ideal for high-performance satellite systems that demand consistent signal quality.
Input and output return losses are typically 20–26 dB, ensuring minimal signal reflection and maximum power transfer — critical for maintaining the integrity of RF chains in professional systems.
The splitter/combiner is available with multiple connector and impedance types:
This range allows integrators to select the best version for their specific application, whether in broadcast, data, or telecommunications environments.
Housed in a compact, durable aluminum enclosure, the COM02L1P-2502 is built for long-term reliability. It includes tapped screw and through-hole mounting options for flexible installation in both fixed and mobile applications.
Each RF port passes both DC power (up to 35V, 500mA) and 10 MHz reference signals, making it compatible with LNBs, BUCs, and reference signal distribution setups.
The unit is designed for indoor use, operating from 0°C to +45°C, and storing safely between -20°C and +75°C. Its rugged build ensures reliability even in fluctuating environments, with humidity tolerance up to 85% non-condensing and an altitude rating of 10,000 feet.
ETL Systems, based in Hereford, UK, is recognized worldwide for its precision RF solutions. The COM02L1P-2502 exemplifies ETL’s engineering excellence — every parameter has been refined for optimal performance.
This splitter/combiner is designed for professional satellite and communication networks that demand the highest levels of signal quality and reliability. It’s used in:
As a passive device, the COM02L1P-2502 offers an extended operational life with no active components to fail. Its reliability translates into reduced maintenance costs and consistent uptime — a key factor for mission-critical applications.
Because it supports DC pass-through, the unit can distribute power to LNBs or BUCs while managing 10 MHz reference signals, making it a highly versatile solution for integrators managing diverse hardware setups.
