KeyLink’s Ku Band Block UP Converter-KBUC11700S47A

As a core component of Ku-band communication, this product boasts superior performance and is precisely adapted to three core fields: In satellite communication, it seamlessly matches Ku-band systems, achieving efficient mid-frequency to high-frequency conversion, and is widely used in ground satellite stations, low-Earth orbit satellite ground terminals, etc., supporting stable communication links in diverse scenarios such as remote areas and maritime vessels; in broadcast communication, its low spurious emissions and low phase noise reduce signal interference, ensuring clear and stable long-distance transmission of broadcast signals; and in radar systems, it is compatible with Ku-band radar equipment, improving detection accuracy and response speed with stable gain and precise conversion capabilities, suitable for low-altitude detection, coastal surveillance, and other low-altitude economic scenarios. Furthermore, the product features IP54 waterproof and dustproof rating and a wide temperature range of -40℃ to +60℃, enabling it to cope with complex outdoor and field environments, further expanding its application boundaries.

The KBUC11700S47A BUC boasts precise parameters and outstanding performance, with significant core highlights: In signal conversion, it offers an input range of 950~2950MHz and an output range of 10.7~12.7GHz, perfectly matching Ku-band requirements. Its 9.75GHz local oscillator frequency, coupled with a typical 75dB linear gain, ensures gain variation is controlled within ±2.5dB typical across the entire frequency band and within the 1GHz range, significantly reducing signal loss. Regarding signal quality, spurious emissions are as low as -45dBc typical, and third-order intermodulation products are -25dBc typical. Phase noise performance is excellent, ranging from -63dBc/Hz to -93dBc/Hz in the 100Hz to 100kHz range, guaranteeing exceptional signal purity. In terms of specifications, it features a 50Ω input impedance, a 2:1 input VSWR, an N-type interface for compatibility with mainstream devices, a saturated output power of 50dBm, and a P-1dB output power. With a typical value of 47dBm, and paired with a 20dB/0.5dB step variable attenuator, it flexibly adapts to different power requirements.

The product boasts outstanding reliability and environmental adaptability, supporting a wide voltage supply of 85~265VAC, 50Hz, with a typical power consumption of 620W. It features a built-in lockout detector that automatically shuts down the transmitter in case of local oscillator lockout, effectively protecting the equipment. For ease of use, it supports remote monitoring and control via Ethernet, with three-color LED indicators displaying the device status in real time. It includes power amplifier switching, gain control, multiple alarm and protection functions for refined management. Measuring 370×280×110mm and weighing 12kg, its compact structure makes it easy to install.

In addition, the product features a built-in reference frequency stabilization system, achieving stability of ±0.02ppm over the temperature range. It supports a 10MHz external reference input and automatically switches to the internal reference when the external reference level is insufficient. The external reference phase noise performance is excellent, reaching a maximum of -135, -145, and -155 dBc/Hz at 100Hz, 1kHz, and 10kHz respectively, comprehensively ensuring stable equipment operation and signal transmission quality.
