Overview
The ARA1400S12C is a Gallium Arsenide (GaAs) integrated circuit designed for CATV reverse path applications. It provides amplification and output level control functions within Set-Top Boxes or headends. The device operates in the 5 to 42 MHz frequency range, delivering typical gain of 38 dB with a noise figure of 6.5 dB. It features an integrated step attenuator offering 15 dB of control range in 3 dB steps. The component is housed in a surface-mount package suitable for high-volume manufacturing.
Feature Summary
- Integrated GaAs MMIC technology for compact RF signal processing
- Built-in step attenuator for precise output level management
- Optimized for low-noise reverse path transmission in hybrid networks
Applications
- CATV Set-Top Box reverse channel amplification
- Hybrid Fiber-Coaxial (HFC) network headend modules
- RF signal conditioning in cable modem termination systems
Procurement Notes
Verify the specific suffix 'S12C' against the manufacturer's latest datasheet revision to ensure pinout and electrical specifications match current design requirements. Confirm RoHS compliance status and moisture sensitivity level ratings prior to assembly planning. Cross-reference the part number with authorized distributors to validate authenticity and traceability documentation.
Selection Notes
Select this component when designing CATV reverse paths requiring integrated gain and attenuation control in a single IC. The GaAs construction supports operation in standard cable TV frequency bands. Ensure the application board layout accommodates the specific thermal and RF grounding requirements associated with surface-mount GaAs MMICs.
Part Context
Anadigics specialized in RF power amplifiers and switches for wireless infrastructure before its acquisition by Broadcom. The ARA1400 series represents legacy components from their CATV product line, focusing on downstream and upstream signal integrity for hybrid fiber-coaxial distribution networks.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Engineering teams should consult official Anadigics or Broadcom documentation for qualified replacements or pin-compatible alternatives.
