DCMA-85: Industrial-grade, high-power 4.9GHz wifi mini-PCI module w/ESD and Surge Protection, AR5414A-B2B

DCMA-85 is the best industrial-grade, high-power 4.9GHz wifi mini-PCI module with accurate high (24.5dBm) and lower (2.5dBm) power control from –40°C ~ +80°C temperature range and integrated RF ESD/Surge protection circuit designed specially for military and government public safety applications.
Both high and lower power control accuracy in –40°C ~ +80°C temperature range can be used to reduce in-band frequency interference of RF signal sources to dramatically improve the data throughput and range performance of Access Points and Clients in high-density WiFi deployments.
RF ESD/Surge protection up to 14KV ensures highest levels of performance and reliability applications in the harshest outdoor environment such as mesh networking, military, bridging, and infrastructure applications.  
Leveraging RF expertise, continuous RD innovation, highly successful DCMA-86 series, DCMA-85 is the only and the best choice of licensed band 4.9GHz high-power mini-PCI WiFi module with built-in ESD/Surge protection circuit valid in the market.

 

 

Key Features

  • Real industrial-grade chipset and components used plus unique design know-how and production calibration reach power control accuracy from 2.5dBm ~ 24.5dBm in –40°C ~ +80°C temperature range.
  • Average power up to 280mW (24.5dBm) with superior sensitivity provide better than average wifi transmission coverage.
  • PA damage protection circuit enables direct antenna switch behind the MMCX connector.
  • Dual power supply plus heat sink design makes critical components temperature cooler by up to 10°C , significantly reduces components aging caused by thermal in high power application to secure long-term performance reliability.
  • Low noise amplifier (LNA) dramatically improves sensitivity provide better than average wifi transmission coverage.
  • Less than 50mV output ripple design ensures high performance while remaining conscious of power efficiency.
  • PA fine-tuning gains balance of linearity and power consumption with enough margin while maintaining adequate Tx power to ensure no major performance degradation over time. 
  • Same EVM on both light and heavy loading maintain lower packet error to increase channel efficiency.
  • Mini-PCI Type IIIA form factor with screw hole is ideal for solid mounting onto motherboard.
  • Linux driver source code sub-license available by project. 
  • Supports 64/128/152-bit WEP encryption, IEEE 802.1x authentication, AES & TKIP, and CCX3.0 encryption.
  • One DIP type MMCX RF connector enables robust assembly and lower loss for external antenna.
  • RoHS compliance meets environment-friendly requirement.
  • Flexible power supply design to easily change from 3.3Vdc (default) to 3.3Vdc+5Vdc by only one on-board resistor shift to meet power budget requirement of different platforms.
