Performance and Compliance Highlights

nn

Gain Control and Signal Integrity

n

The 900/2100 dual band pico selective repeater offers precise gain adjustment capability with a range of ≥25 dB in 1 dB steps, ensuring fine-tuned signal amplification tailored to specific environments. The gain adjustable error remains within tight tolerances—≤1 dB for adjustments from 0 to 20 dB, and ≤1.5 dB for adjustments beyond 21 dB—guaranteeing consistent performance. The Automatic Level Control (ALC) circuit maintains output stability even under varying input conditions: when adding up to 10 dB at maximum output level, the output variation is ≤±2 dB; for additions exceeding 10 dB, the variation remains ≤±2 dB or the circuit automatically shuts off to prevent distortion. This feature is critical for protecting downstream equipment and ensuring signal purity.

Noise and Linearity Performance

n

With a noise figure of ≤6 dB at maximum gain, the repeater minimizes signal degradation, preserving the original signal-to-noise ratio. The low time delay of ≤5.0 μs ensures minimal latency, essential for real-time applications like voice calls and video streaming. The VSWR of ≤2.0 indicates excellent impedance matching, reducing reflections and power loss. Ripple within the band is kept under ≤4 dB, flattening the frequency response for uniform amplification across the operational spectrum. Out-of-band restraint is robust: from 2.5 MHz to 5 MHz offset, attenuation is at least 40 dB, and beyond 5 MHz, it rises to ≥60 dB, effectively suppressing interference from adjacent channels.

nn

Regulatory Compliance and Reliability

n

Every aspect of the 900/2100 dual band pico selective repeater complies with rigorous 3GPP standards. Spurious emission, spectrum emission mask, and ACRR all meet the requirements of 3GPP TS 36.106 and TS 36.143, guaranteeing that the repeater operates without causing harmful interference to other wireless services. Frequency stability is exceptional at ≤0.05 ppm, ensuring accurate frequency alignment even in varying environmental conditions. The EVM (Error Vector Magnitude) is capped at ≤8%, preserving modulation quality and data integrity for high-speed LTE and 5G communications. These specifications collectively position this pico repeater as a reliable, future-proof solution for enhancing cellular coverage in demanding environments.
