DCMA-86P2: 5.9GHz DSRC wireless mini-PCI, AR5414A-B2B
DCMA-86P2 is the first 5.86 – 5.92GHz industrial-grade high power wireless mini-PCI designed specifically to support communications for vehicle-to- vehicle (V2V) or vehicle-to-roadside (V2R) applications using 5.9GHz DSRC protocol.
Unique combination of dedicated temperature compensated crystal oscillator (TCXO) for OSC source, industrial-grade wireless chipset and components, and more than 7 years Atheros chipset / RF design experience enables DCMA-86P2 to support 1). less than ± 10ppm transmitted center frequency tolerance, 2). less than 10dBm antenna input power and 23dBm EIRP over temperature range –40°C ~ +85°C and 3). type I and type II receiver’s alternate adjacent channel rejection, which almost comply with ASTM E2213 requirement.

Key Features
- Dedicated temperature compensated crystal oscillator (TCXO) used to ensure less than +/- 10ppm transmitted center frequency deviation over wide –40ºC ~ +85ºC temperature range.
- Real industrial-grade chipset and components with unique design / production calibration know-how enable power control accuracy from 2.5dBm ~ 24dBm over wide –40°C ~ +85°C temperature range.
- Dedicated high rejection Rx filter operates in 5.86-5.92 GHz frequencies used to meet ASTM E2213.03 Clause 8.10.2. type I adjacent/alternate adjacent and type II alternate adjacent channel rejection requirement.
- RF ESD and Surge protection up to 14KV ensures highest level 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 to ensure 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.
- Max. 7dB sensitivity improvement at 5.92GHz/13.5Mbps/5MHz BW than Atheros MB62 reference design.
- Mini-PCI Type IIIA form factor with screw hole is ideal for solid mounting onto motherboard to against vibration.
- 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?
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.
