GREENSBORO, N.C. — RF Micro Devices, Inc. (Nasdaq: RFMD), a global leader in the design and manufacture of high-performance semiconductor components, today announced the release of the S510075-33Z out-of-band tuner for use in cable set-top box and digital cable ready television applications. The S510075-33Z is designed to provide original equipment manufacturers (OEMs) with an optimum blend of performance and energy efficiency while also meeting the increasing performance requirements of cable devices.

The highly integrated S510075-33Z consists of an input automatic gain control (AGC) amplifier, a mixer and an AGC video amplifier, delivering a 60 percent size reduction and 25 percent reduction in power consumption compared to the previous generation S510065-55Z. The S510075-33Z leverages RFMD’s unique innovations in silicon CMOS design techniques to deliver these improvements while maintaining the critical, low distortion performance necessary for end market applications.

As the leading provider of out-of-band tuners, RFMD(R) is committed to bringing our customers innovative new products, said Alastair Upton, general manager of RFMD’s Broadband and Consumer Business Unit. Improvements in size reduction and efficiency, like those found in the S510075-33Z, are becoming critical requirements for set-top box manufacturers as they increase the functionality and resulting component content of new devices. In 2008 RFMD will expand our broad portfolio of CATV products to include new generations of active splitters, programmable return path amplifiers and line amplifiers.

Features of the S510075-33Z include:

  • 3.3 V single supply operation
  • Low power consumption: 300 mW
  • Low distortion: -50dBc @ 1 VPP
  • 70 dB total conversion gain
  • 55 dB total gain control range
  • Low LO to RF leakage

The S510075-33Z is housed in a compact 3 x 3 mm, 16 lead, RoHS compliant QFN package, and samples are available immediately. Based on design win activity RFMD anticipates volume shipments of the S510075-33Z will commence in the current calendar year.
