The UPB1502GR-E1 is a silicon monolithic integrated circuit manufactured by NEC. Similar to the UPB1502GR, it is designed for use in direct broadcast satellite (DBS) receivers as a low noise block downconverter (LNB). It amplifies and downconverts the high-frequency signals received from the satellite dish to a lower intermediate frequency (IF) for processing. The '-E1' suffix likely indicates a specific revision or packaging variant.
Applications
- Direct Broadcast Satellite (DBS) Receivers: Serves as the front-end LNB in satellite receivers for signal amplification and downconversion.
- Satellite TV Systems: A vital component in satellite television receiving systems.
- Satellite Communication Systems: Utilized in satellite communication equipment for signal reception and processing.
Features
- Low Noise Figure: Minimizes noise introduced during signal amplification.
- High Gain: Amplifies weak satellite signals for improved reception.
- Low Current Consumption: Reduces power dissipation within the LNB.
- High Image Rejection: Suppresses unwanted image frequencies, enhancing signal clarity.
- Integrated Local Oscillator (LO): Simplifies design by integrating the LO on the chip.
Benefits
- Improved Signal Quality: Provides a better signal-to-noise ratio for clearer reception due to its low noise figure and high gain.
- Simplified System Design: The integrated LO reduces the number of external components required.
- Reduced Power Consumption: Contributes to more energy-efficient LNB designs.
- Enhanced System Performance: High image rejection results in improved receiver performance.
- Compact LNB Design: Facilitates the creation of smaller and more efficient LNBs due to the integrated functionality.
Specifications
The UPB1502GR-E1 is designed for operation in the Ku-band frequency range, typically covering 10.7 GHz to 12.75 GHz. The noise figure is typically in the range of 0.8 dB to 1.2 dB. The gain is usually between 50 dB and 60 dB. The intermediate frequency (IF) output is generally around 950 MHz to 2150 MHz. The supply voltage is typically +5V. As with the UPB1502GR, it is commonly packaged in a small surface-mount package.
