What is Passive Intermodulation (PIM) and are there low PIM antennas for 4G in-building wireless networks?

In 4G/LTE, 3G and GSM networks, RF perfomance can be significantly affected by PIM (Passive Intermodulation) issues. In simple terms, PIM is a RF interference problem where 2 or high power signals mix across a passive component such as an antenna, connector, RF cable or duplexer. The presence of PIM in the transmission path may result in lower data throughputs, in calls being disconnected or dropped or limit the overall capacity/performance of the network.

Especially in new wireless in-building environments, we are seeing the advent of specific low PIM antennas which combat the problems of PIM and help to ensure that network performance is optimised.

The first low PIM 4G/Multiband antenna available through SAS in the UK is the Laird CMD69273P - a low PIM ceiling mount antenna covered worldwide 4G/cellular frequencies from 700-2700 MHz. Housed in a discrete radome, the CMD69273P is an effective performer for multi-band in-building deployments. Small quantities can be purchased via our webshop.

CMD69273P

For a directional 4G/Multiband MIMO antenna with low PIM capability, the Laird PAS69278P has been announced. It is a wide-band dual-port panel antenna with slant 45 polarization that covers the domestic LTE700/Cellular/PCS/AWS/MDS and global GSM900/GSM1800/UMTS/LTE2600 bands.

PAS69278P MIMO Low Pim Directional antenna

This directional antenna offers a minimum of 8 dBi gain on both antenna elements and is terminated in N-Female connectors.

PCTEL announces a number of in-building low PIM solutions pending.

PCTEL has also announced a number of new Low PIM antennas pending release so please contact us with your low PIM antenna requirements.
