The UPB1507GV-E1-A is a silicon monolithic integrated circuit manufactured by California Eastern Laboratories (CEL), often used as a Low Noise Block Downconverter (LNB) for direct broadcast satellite (DBS) receivers. It serves to amplify and downconvert the high-frequency signals received from the satellite dish to a lower intermediate frequency (IF) suitable for subsequent processing.
Applications
- Direct Broadcast Satellite (DBS) Receivers: Functions as the front-end LNB, amplifying and downconverting satellite signals for reception.
- Satellite TV Systems: A critical component in satellite television receiving systems.
- Satellite Communication Systems: Used in satellite communication equipment for processing received signals.
Features
- Low Noise Figure: Minimizes added noise during amplification, leading to a cleaner signal.
- High Gain: Amplifies weak satellite signals for improved reception.
- Low Current Consumption: Reduces power dissipation.
- High Image Rejection: Suppresses unwanted image frequencies, improving signal clarity.
- Integrated Local Oscillator (LO): Simplifies design by including the local oscillator function within the chip.
Benefits
- Improved Signal Quality: The low noise figure and high gain result in a better signal-to-noise ratio, providing clearer reception.
- Simplified System Design: The integrated LO reduces the need for external components.
- Reduced Power Consumption: Contributes to more energy-efficient LNB designs.
- Enhanced System Performance: High image rejection leads to better overall receiver performance.
- Compact LNB Design: Facilitates the creation of smaller and more efficient LNBs due to the single-chip integration.
Specifications
The UPB1507GV-E1-A is designed for operation in the Ku-band frequency range (10.7 GHz to 12.75 GHz). The noise figure typically ranges from 0.8 dB to 1.2 dB. The gain is commonly between 50 dB and 60 dB. The intermediate frequency (IF) output usually spans from 950 MHz to 2150 MHz. The supply voltage is typically +5V. It is generally available in a small surface-mount package, facilitating integration into LNB designs.
