IDT Intros Low-Distortion Mixer for 4G Base Station Transceivers

Integrated Device Technology introduced a low-power, low-distortion diversity mixer for 4G base stations. The new device reduces distortion while simultaneously reducing power consumption in LTE and time-division duplexing (TDD) wireless communication architectures. Compared to competitive solutions, the IDTF1162 improves IM3 distortion by 18 dB while simultaneously reducing power consumption by 40 percent (1150 mW typical). These attributes ease heat-sinking requirements on the radio card and allow infrastructure vendors to utilize higher average frontend gain settings, which results in higher signal-to-noise ratio (SNR). Improved receiver SNR of up to 0.4 dB benefits cellular operators by expanding the coverage area and improving the available data rates to users on the periphery of the cell.

IDT said its new LTE mixer is an important RF product in its strategy to provide the industry with a complete radio card signal chain, from the antenna to the digital signal processors (DSPs).
