LNBH23LQTR General Description

The LNBH23LQTR is a low-noise block down-converter (LNB) with integrated RF, DC, control and monitoring interfaces for satellite receiver applications. This device features a very low noise figure of 0.3 dB, making it ideal for high-performance satellite reception. It operates over a wide frequency range from 250 MHz to 2350 MHz, covering both Ku-band and C-band frequencies.The LNBH23LQTR is designed to provide high linearity and low power consumption, making it suitable for use in a wide range of satellite television and communication systems. It also includes a built-in 22 kHz tone generator and DiSEqC 2.0 compatibility for communication with satellite receivers.In terms of packaging, the LNBH23LQTR is housed in a compact QFN package measuring 4x4 mm, making it easy to integrate into smaller satellite receiver designs. It is also RoHS compliant, ensuring it meets environmental regulations for electronics manufacturing.

Key Features

The LNBH23LQTR is a dual low-noise block downconverter (LNB) supply and control voltage regulator with an integrated step-up DC-DC converter

It features protection functions such as overtemperature and overcurrent, an integrated DC-DC step-up converter, and low-dropout linear controllers for both LNB outputs

The device also offers high output voltage accuracy and stability

Application

The LNBH23LQTR is commonly used in satellite communication systems for receiving, amplifying, and down-converting signals from satellite dishes

It can also be utilized in digital TV systems, VSAT (Very Small Aperture Terminal) systems, and broadcast communication systems for noise figure improvement and signal processing
