New IDT mixer is ideal for LTE and TDD systems

Integrated Device Technology, (IDT) has 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 has been an eagerly anticipated addition to our portfolio of dual mixers and it delivers the high performance customers rely upon 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.”
