The MaxLinear MxL11xx is an all-CMOS, single-chip broadband microwave transceiver product family that can support operation of all licensed and unlicensed bands from 5 GHz to 45 GHz, including all ETSI-defined channel spacing options from 5MHz to 224MHz.
The MxL11xx features built-in Full Spectrum Capture (FSC) technology and supports channel aggregation mode, enabling a second channel with any channel spacing to be processed within the same IC.
It is important to take into account that traditionally used intensity modulation with non-return-to-zero (NRZ) coding is not able to provide sufficient quality of the signal with the increasing of data rate or reducing channel spacing.
From the results the effect of four wave mixing on the system is presented under different configurations such as input power per channel and channel spacing mainly.
4 and 45MHz MCF devices offer channel spacing of 12.
For forward visibility, a three-stage mast incorporates a low profile primary cylinder, single lift chain and wide channel spacing, while secondary lift chains and auxiliary hydraulics are mounted at 90[degrees] behind the channels.
As the channel spacing was increased, the output voltage of the detector decreased.
The RF transceiver fully meets the requirements for 25 kHz channel spacing and adjacent channel power of <-37 dBm, and it is suitable for applications operating in the 433 MHz--868 MHz--915 MHz band such as social alarms, security, automatic metering, services and controls, as well as remote keyless entry.
Other features include multiple-tone signaling, both wide and narrow channel spacing, and three steps of output power.
The radio itself is tuned via software, so it can be programmed to find signals mechanically tuned radios can't, and the variable IF filter algorithm automatically adjusts to either 100 KHz (European) or 200 KHz (North American) channel spacing.
Fiberspace is dedicated to providing high performance, low-cost products for metro and long haul applications requiring very close channel spacing.
