The UPC1100GS is a wideband amplifier IC manufactured by NEC. It is similar to the UPC1100G but available in a surface mount package, making it suitable for more compact designs. It operates in the VHF and UHF bands and is commonly used in TV tuners and communication equipment as an RF amplifier. Its main purpose is to amplify signals with minimal added noise and distortion.

Applications:

• TV Tuners: RF amplification stage in analog TV tuners (surface mount applications).
• VHF/UHF Receivers: Front-end amplifier for radio receivers (surface mount applications).
• Communication Equipment: General purpose amplification in communication circuits (surface mount applications).

Features:

• Wide Bandwidth: Operates across VHF and UHF frequencies.
• Low Noise Figure: Minimizes added noise during amplification.
• High Gain: Provides adequate signal amplification.
• Surface Mount Package: Enables compact circuit designs.

Benefits:

• Improved Reception: Amplifies weak signals for better reception.
• Reduced Noise: Maintains signal clarity by minimizing noise.
• Compact Design: Surface mount package saves board space.

Technical Specifications:

The UPC1100GS comes in a surface mount package (SOP). Typical gain is around 18dB. Noise figure is generally below 5dB. It operates on a single voltage supply. Always consult the datasheet for specific electrical characteristics and package details for accurate design.
