The UPB1502GR is a silicon monolithic integrated circuit manufactured by NEC, primarily intended for use in direct broadcast satellite (DBS) receivers as a low noise block downconverter (LNB). It is designed to amplify and downconvert the high-frequency signals received from the satellite dish to a lower intermediate frequency (IF) suitable for processing by the receiver.

Applications

• Direct Broadcast Satellite (DBS) Receivers: Used as the front-end LNB to amplify and downconvert satellite signals.
• Satellite TV Systems: A critical component in satellite television receiving systems.
• Satellite Communication Systems: Employed in satellite communication equipment for signal reception.

Features

• Low Noise Figure: Minimizes noise introduced during signal amplification, resulting in a clearer signal.
• High Gain: Amplifies weak satellite signals for better reception.
• Low Current Consumption: Reduces power dissipation in the LNB.
• High Image Rejection: Suppresses unwanted image frequencies, improving signal quality.
• Integrated Local Oscillator (LO): Simplifies the design by integrating the LO on the chip.

Benefits

• Improved Signal Quality: Low noise figure and high gain provide a better signal-to-noise ratio, resulting in clearer reception.
• Simplified System Design: Integrated LO reduces the need for external components, simplifying the LNB design.
• Reduced Power Consumption: Low current consumption allows for more energy-efficient LNB designs.
• Enhanced System Performance: High image rejection improves overall receiver performance.
• Compact LNB Design: Integration of multiple functions into a single chip enables smaller and more efficient LNBs.

Specifications

The UPB1502GR operates in the Ku-band frequency range (typically 10.7 GHz to 12.75 GHz). The low noise figure is typically around 0.8 dB to 1.2 dB. The gain is usually in the range of 50 dB to 60 dB. The intermediate frequency (IF) output is typically around 950 MHz to 2150 MHz. The supply voltage is typically +5V. It's commonly packaged in a small surface-mount package for easy integration into LNB designs.
