Newest Member of the Fast-Growing IDT RF Portfolio is Ideal for LTE and TDD Systems

October 27, 2014

SAN JOSE, Calif., Oct. 27, 2014 – Integrated Device Technology, Inc. (IDT®) (NASDAQ: IDTI) today introduced a new low-distortion, low-power radio frequency (RF) mixer, delivering RF technology that reduces distortion in LTE and TDD systems while minimizing power consumption. The latest addition to IDT’s fast-growing portfolio of RF products, the F1178 improves IP3O by up to 8 dB and reduces power consumption up to 30 percent vs. competing mixers.

A member of IDT’s “Zero-Distortion” family of dual mixers, the IDT F1178 is a high-performance RF to IF mixer designed to operate with a single 5 V supply. The mixer is optimized for operation in receivers with RF bands from 3300 - 3800 MHz. The chip is ideal for base station radio cards, repeaters, distributed antenna systems and microwave backhaul equipment.

Very low power consumption eases heat-sinking requirements on radio cards, and ultra-high IP3 allows for high- gain frontends. The F1178 delivers fast settling from power up with constant LO impedance, allowing customers to power the mixer down in between TDD Rx slots, further reducing power consumption.

“This eagerly anticipated addition to our portfolio of popular dual mixers delivers the high performance customers rely upon from us to rapidly deploy 3.5 GHz band solutions. With its extremely low IM3 distortion, the F1178 can significantly improve radio card performance,” said Chris Stephens, IDT’s senior director of Wireless Product Definition and Marketing. “With the F1178 dual mixer, customers can improve signal-to-noise ratio by running their system with higher RF gain while maintaining excellent IM3 distortion, just like they do at the lower frequency bands with our mixers.”

The F1178 offers:

  • Excellent channel isolation of more than 44 dB
  • Fast settling power down mode for TDD systems
  • RF range from 3300 - 3800 MHz for bands 42, 43
  • 9.0 dB gain
  • Ultra linear +38 dBm IP3O
  • Low 9.0 dB noise figure (NF)
  • 200 ohm output impedance
  • High +10.7 dBm P1dBI
  • Pin compatibility with IDT’s lower frequency dual mixer offerings
  • Low power consumption of less than 1.4 Watts


The device is sampling to qualified customers.
