RFSA3013 and RFSA3023 CATV Voltage-Controlled AttenuatorsRFMD’s new RFSA3013 and RFSA3023 are fully monolithic analog voltage-controlled attenuators (VCAs) featuring exceptional linearity over a 30dB minimum gain control range. These VCAs also feature internal temperature compensation that provides an attenuation profile highly insensitive to temperature changes. Each VCA is controlled by a single positive control voltage with on-chip DC conditioning circuitry. The slope of the control voltage versus gain is selectable. These VCAs have been characterized for 75Ω CATV applications over the full attenuation and frequency ranges with no external matching components required. The components are offered in a compact 3mm x 3mm QFN package.

Features
  • Broadband 50MHz to 3000MHz Frequency Range
  • >30dB Attenuation Range
  • +50dBm IIP3
  • +80dBm IIP2
  • Distortion -65dBc CSO and -70dBc CTB for 112 Channel 39dBmV Input
  • P1dB >+30dBm
  • Supply Current 1mA
  • Linear-in dB Control Characteristic
  • Internal Temperature Compensation
  • Class 1C ESD (1000V)
Applications
  • Cable Modems
  • CATV
  • High Linearity Power Control
These products are now available in production quantities. Pricing begins at $3.94 each for 100 pieces.
