LNB controllers for DBS

28 April 2010 Telecoms, Datacoms, Wireless, IoT

Diodes Incorporated has announced the introduction of a new family of low noise block (LNB) controllers for direct broadcast satellite (DBS) applications.

In smaller packaging and operating at lower voltages and higher levels of accuracy than previous generations, the six new devices aim to increase the efficiency and reliability of LNB designs while reducing overall size. These controllers have proven in some cases to use less than 1% of total LNB current, while their low supply voltage operation ensures an efficiency improvement when used with DC-DC converters.

Packaging is now the ultra thin QFN style, enabling a reduction in PCB size and off-board height requirement. Offering accurate and flexible control and internal filtering, the new controllers completely eliminate false switching and support a wide range of set-top box designs and specifications. The six controllers have been designed to exceed the latest DBS broadcast specifications.

The ZNBG3118 provides bias control and protection for up 3 GaAs and HEMT FET low noise amplifiers. The controller integrates an accurate voltage detector for LNB polarisation channel selection and an advanced tone detector for local oscillator selection for band switching. The ZABG4002 and ZABG6002 are low power fixed bias controllers for 4 and 6 stage FET low noise amplifiers respectively, providing each FET with an independent protected negative gate voltage and positive drain voltage with user programmable drain current selectable from 0 to 15 mA.

Offering a choice of high and standard accuracy polarisation voltage detection are the ZLNB2015 and ZLNB2016 advanced DBS dual voltage and tone detectors. Optimised for low supply current and wide operating voltage, the devices also offer excellent interference rejection while keeping application cost down. Finally, the ZLNB254 is a dual channel DiSEqC interface for LNBs and satellite distribution systems. The IC provides two highly accurate DiSEqC detectors, which convert the DiSEqC signals into logic level representations, enabling simple and reliable processor monitoring.
