Low-Band RF Mixer Enhances Mobile Experience by Reducing Intermodulation Distortion

The IDT F1102 is a low-power, low-distortion dual 400 - 1000 MHz RF-to-IF mixer that improves IM3 by over 15 dB, while simultaneously reducing power consumption by over 40 percent compared to standard mixers. These performance qualities result in better signal-to-noise ratio for improved quality of service, along with lowered heat dissipation to ease heat-sinking requirements in the densely-populated radio card enclosure (1.15 W at 5 V and up to +43 dBm IP3O). Offering unmatched performance and efficiency, the F1102 is ideal for multi-carrier, multi-mode 4G LTE and EGSM BTS systems.

“Having observed the superior performance of our high- and mid-band mixers, our customers are demanding this product,” said Tom Sparkman, vice president and general manager of the Communications Division at IDT. “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 U.S. cellular bands. With our broad portfolio of high-performance, low-power variable gain amplifiers, industry-leading timing, serial switching, data conversion and data compression products, IDT is a one-stop shop for communications signal chain solutions.”

As with other members of IDT’s mixer family, the F1102 offers fast settling time and a constant local oscillator input impedance in power-up and -down modes. This allows customers to power-down the mixer between time-division duplex receiver slots, further reducing power consumption. In addition, the IDTF1102 can be used with either high-side or low-side injection, and is pin-compatible with existing devices on the market, offering a compelling upgrade option.

The IDT F1102 is currently sampling to qualified customers and is available in a 36-pin 6x6 mm QFN package.
