RF to IF mixer reduces power consumption by 40%

IDT has introduced a low band rf mixer designed to enhance mobile connectivity by reducing intermodulation distortion in the crowded frequency spectrum for 4G LTE, 3G, and 2G systems.
The new Zero Distortion base transceiver station (BTS) diversity mixer is optimised for improved system third order intermodulation distortion (IM3) performance with reduced power consumption, covering the 450MHz, Long Term Evolution (LTE) and extended global system for mobile communications (EGSM) frequency range.
The IDT F1102 is a dual 400 to 1000MHz rf to IF mixer that is said to improve IM3 by over 15dB, while reducing power consumption by over 40% compared to standard mixers. IDT says this results in better signal to noise ratio (SNR) for improved quality of service (QoS), along with lowered heat dissipation to ease heat sinking requirements in the densely populated radio card enclosure (1.15W at 5V and up to 43dBm IP3O).
"Our Zero Distortion technology enables the customer to increase the radio card's front end gain to improve SNR, while simultaneously reducing distortion in the crowded EGSM and US cellular bands," said Tom Sparkman, vp and general manager of the communications division at IDT.
