सिंहावलोकन:
हमारा Multi-Band RF Bandpass Filters are precision-engineered components designed to meet the demanding requirements of modern RF systems across multiple frequency bands, including L-band (1150 MHz), S-band (1710 MHz), C-band (2310 MHz), and extended bands such as 1400 MHz. These filters provide precise passband control, low insertion loss, high return loss, और superior stopband rejection, ensuring high-fidelity signal transmission and reception in complex RF environments.
डिजाइन दर्शन
The design of these filters focuses on optimizing signal integrity while minimizing interference from unwanted frequencies. Each filter is constructed using 6061 aluminum alloy housings for mechanical robustness, H59 copper resonant columns for precise frequency response, और LY12 aluminum covers to ensure structural stability. Connector assemblies use H59 copper with ternary plating, and tuning screws are made from H62 copper, all complemented by stainless steel mounting screws for corrosion resistance and durability.
Operating Environment
These filters are designed to operate reliably in temperatures ranging from -30डिग्री सेल्सियस से +70 डिग्री सेल्सियस, making them suitable for harsh outdoor environments, industrial facilities, and high-altitude installations. The compact and lightweight form factor (170–180 × 36 × 25–30 mm; 350 जी) allows easy integration into existing RF systems, whether mounted on a rack, bench, or within equipment enclosures.
सत्ता चलाना
Depending on the model, these filters can handle 50 W to 100 W of RF power, making them suitable for medium-power systems, including satellite communication uplinks and radar transmitters.
Connector Standardization
All models feature 50 Ω impedance और N-Female connectors, ensuring compatibility with standard RF equipment and systems.
These filters are widely used in applications where signal purity, system reliability, and interference suppression are critical, including satellite communication, राडार, telecommunications, industrial RF systems, and R&D laboratories.
