Low-PIM Solutions

Introduction:

K&L is devoted to developing and offering a set of RF solutions to support trends in emission monitoring for high power (base station) and low power (chipset) OEMs. OEMs make emission monitoring measurements during product development and during certification prior to deployment. This Low-PIM solutions page presents an overview of K&L product support for broadband emission monitoring, general information on K&L's low-PIM capabilities (including block diagrams, pictures, and test results), and links to low-PIM parts and part specifications, and is intended as a companion to our LTE Products section and our Test Set Solutions products page.

 

Emission Monitoring Overview

Emission monitoring is critically important to OEMs for a variety of reasons. Considerations pushing technical capabilities and cost-effectiveness in the current base station and chipset marketplaces include:

  • separation of IM products from carriers while operating at full power,
  • protecting devices from energy bounce-back,
  • broad-band spurious emission,
  • TX/RX measurement, and
  • interferer/interference tests, including interactions with satellite communication (GPS, Inmarsat, etc.).

For effective monitoring, high-power base station OEMs and low-power chipset OEMs require expensive test boxes operating in the 3GPP and LTE bands, respectively. Typical base station requirements are 100W CW, 1KW Peak, and low PIM of 156dBc for 2x+43dBm. Typical chipset requirements are 0.5W CW and IM of 100dBc for 2x+33dBm.
