Configurable DAS Solutions


Precision Step Variable Step Attenuating Trays

API Technologies' attenuator trays for DAS systems are optimal for applications where the DAS head end requires one simplex transmit and one simplex receive per sector, per technology. Our solutions allow you to attenuate two Rx paths independently for maximum flexibility.

Our line of low PIM precision variable step attenuator trays is available in standard RF path configurations of 3, 4, 5, or 6 input/output ports, with custom configurations available to accommodate up to 12 ports.

All components in the unit, including the duplexer and cable attenuator/loads handling power have been upgraded to low PIM.

Features & Specifications

Features:
  • DAS solutions configured to meet user requirements
  • Fully integrated solutions available: from small site to custom DAS conditioning trays
  • Site- specific requirements and custom configurations available
  • 100% compliant with neutral host requirements
  • Additional attenuation can be added to the output to satisfy specific vendor requirements

Full Line of DAS Solutions for Increased Network Performance

Neutral Host Venue, Outdoor, and In-Building Solutions

API Technologies offers a complete line of standard and user-configurable DAS and low PIM filter products for today’s growing DAS infrastructure. These Distributed Antenna Systems (DAS) deliver un-compromised performance with a modular design that allows you to deploy only what you need today, and inexpensively add on or upgrade as your needs require.

DAS Configurations


API Technologies offers four different DAS configurations, or formats, which can be balanced to provide the optimum solution for any given application.

Single-input-single-output (SISO):

Single input signal and a single output signal.

Single-input-multiple-output (SIMO):

Single input signal (the transmitter has a single antenna) and more than one output signal.

Multiple-input- single -output (MISO):

Multiple input signals and a single output signal (the receiver has a single antenna).

Multiple-input-multiple-output (MIMO):

Multiple input and output signals, and form the most general of the four classes. They have dual capability of combining the SIMO and MISO technologies.
