Attenuator Hilitand 1-3800MHz Module 0-31dB Adjustable 1dB Step

Description

Product Overview

The Hilitand 1-3800MHz variable attenuator module is engineered to meet the demanding requirements of modern fiber optic and radio‑frequency testing environments. Constructed from high‑grade copper and housed in a CNC‑machined shell, the unit offers exceptional thermal stability and mechanical robustness, ensuring consistent performance over extended periods of operation. With an attenuation range of 0 to 31dB and a fine 1dB step size, users can achieve precise signal level control, essential for calibration, gain‑setting, and signal‑to‑noise ratio optimization. The module features a standard RP‑SMA interface, providing seamless compatibility with a wide array of test equipment, including spectrum analyzers, network analyzers, and optical power meters. Power is supplied via a convenient miniUSB 5V connection, eliminating the need for external power supplies and simplifying integration into portable test rigs. Input and output impedances are tightly controlled at 50 Ω, preserving signal integrity and minimizing reflections across the operating frequency band of 1 MHz to 3.8 GHz. Detailed specifications such as weight (2.82 oz), dimensions (4.06 × 4.06 × 1.26 in), and material composition are listed to aid system designers in mechanical and thermal planning. The module’s design emphasizes user‑friendly operation: a simple OK key confirms settings, while dedicated + and – keys allow rapid adjustment of attenuation values, with real‑time digit display for immediate feedback. This combination of precision, durability, and ease‑of‑use makes the Hilitand attenuator a reliable choice for both laboratory engineers and field technicians seeking high‑performance signal attenuation.

Usage

In practical applications, the Hilitand attenuator excels across a broad spectrum of scenarios. Laboratory environments benefit from its fine‑step attenuation when performing detailed gain‑flatness measurements, where incremental adjustments are required to map system response accurately. Field deployments, such as on‑site fiber optic link testing or mobile RF troubleshooting, appreciate the module’s compact form factor and low power consumption, allowing it to be powered directly from a laptop or handheld device via the miniUSB connector. The universal RP‑SMA interface ensures that the attenuator can be quickly integrated into existing test setups without the need for additional adapters, reducing downtime and simplifying inventory management. Engineers working on antenna design can use the module to simulate path loss and evaluate system performance under varying attenuation conditions, while telecommunications technicians can employ it to balance signal levels in multiplexed networks, preventing overload and ensuring optimal data throughput. Its robust copper construction also makes it suitable for harsh environments where temperature fluctuations and mechanical vibrations are common, such as outdoor antenna farms or industrial monitoring stations. By providing reliable, repeatable attenuation, the Hilitand module helps users maintain compliance with industry standards, improve measurement accuracy, and accelerate troubleshooting cycles.
