The UPB1618GS-E1 is a silicon monolithic integrated circuit from NEC. This device is designed as a high-performance downconverter for satellite receiver applications. It is commonly employed in LNBs (Low Noise Block downconverters) to amplify and downconvert signals received from satellite dishes to lower intermediate frequencies suitable for processing by the receiver.

Applications

• Direct Broadcast Satellite (DBS) Receivers: Used in LNBs to downconvert Ku-band signals.
• Satellite TV Systems: An integral part of satellite television reception equipment.
• Satellite Communication Systems: Employed in satellite communication systems for signal processing.

Features

• High Conversion Gain: Provides strong signal amplification during downconversion.
• Low Noise Figure: Minimizes noise introduced during the downconversion process.
• Integrated LO (Local Oscillator): Simplifies system design by including the local oscillator.
• Low Current Consumption: Reduces power requirements for LNB applications.
• Compact Package: Enables smaller and more efficient LNB designs.

Benefits

• Improved Signal Quality: High conversion gain and low noise figure ensure a clearer, stronger signal.
• Simplified System Design: The integrated LO reduces the need for external components.
• Reduced Power Consumption: Low current consumption contributes to energy-efficient LNBs.
• Enhanced System Performance: Enables robust and reliable satellite signal reception.
• Compact System Size: Facilitates smaller and more efficient LNB designs.

Specifications

The UPB1618GS-E1 is designed to operate within the Ku-band frequency range, typically from 10.7 GHz to 12.75 GHz. The conversion gain is usually around 25 dB to 35 dB. The noise figure is in the range of 1.5 dB to 2.5 dB. The LO frequency is internally set for downconversion to an intermediate frequency (IF) typically ranging from 950 MHz to 2150 MHz. The supply voltage is commonly +5V. The device is usually packaged in a small surface-mount package for easy integration into LNB designs.
