DCMA-86P2: industrial grade, high power 5.86~5.92GHz wifi mini-PCI module for 802.11p/DSRC application, AR5414A-B2B

DCMA-86P2 is the first wifi mini-PCI designed specifically to support 802.11p/DSRC application in a vehicular environment. Industrial grade high power 5.86 ~ 5.92GHz wifi mini-PCI module using a dedicated temperature compensated crystal oscillator (TCXO) for OSC source, DCMA-86P2 overcomes the extra challenges of ±10ppm center frequency tolerance, power control accuracy in temperature range –40ºC ~ +85ºC, stringent adjacent channel rejection (ACR) and fading impacts per ASTM E2213.03 requirement. RF ESD/Surge protection up to 14KV ensures highest levels of performance and reliability in the harshest outdoor environment such as vehicle-to-vehicle (V2V) and vehicle-to-roadside (V2R) applications.

 

Key Features

  • Dedicated temperature compensated crystal oscillator (TCXO) ensures frequency deviation within ± 10ppm in –40ºC ~ +85ºC temperature range.
  • Real industrial-grade chipset and components used plus unique design know-how and production calibration reach power control accuracy from 2.5dBm ~ 24dBm in –40°C ~ +85°C temperature range.
  • Dedicated high rejection Rx filter operates in 5.86-5.92 GHz frequencies to increase alternate adjacent channel rejection (ACR) to maximize the throughput and meet ASTM E2213.03 Clause 8.10.2.
  • RF ESD and Surge protection up to 14KV ensure highest levels of performance and reliability in the harshest outdoor vehicular deployments.
  • Average power up to 251mW (24dBm) meets DRSC Class C output requirement and provides superior wifi coverage.
  • 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.
  • PA fine-tuning gains balance of linearity and power consumption with enough margins 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.
  • Less than 50mV output ripple design ensures high performance while remaining conscious of power efficiency.
  • Outstanding sensitivity performance.
  • Mini-PCI Type IIIA form factor with screw hole is ideal for solid mounting onto motherboard to against vibration.
  • Linux driver source code sub-license valid 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.

Why AR5414A B2B

Why AR5414A B2B required for Industrial Applications?

 

5414A B2B & 5414A

Industrial grade AR5414A B2B chipset is for applications in the most-demanding environments in the world. It must withstand tremendous temperature, humidity, and ambient air ranges. By contrast, the commercial grade AR5414A is for applications generally placed in a climate-controlled environment that is carefully monitored to ensure optimum performance.

1. In normal temperature range 0 –60°C: the power control accuracy of wifi modules using either AR5414A B2B or AR5414A chipset can be the same precise for a professional company as Unex.

2. At temperature of –15°C, -40°C or +80°C, obvious power control accuracy differences can be found on the test result of AR5415A B2B and AR5414A.
