DNMA-H92: extended-temperature high-power 802.11n a/b/g wifi 2x2 mini-PCI module w/ESD and Surge Protection, AR9220

DNMA-H92 is an extended temperature high-power 802.11n a/b/g 2x2 wifi mini-PCI module integrated with 12KV RF ESD/Surge protection circuit designed specifically to enable highest - performance and reliability in the harshest outdoor environment such as mesh networking, military, bridging, and infrastructure applications.
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, less than 50mV output ripple design ensures high performance while remaining conscious of power efficiency, low noise amplifier (LNA) dramatically improves sensitivity, and PA damage protection circuit enables direct antenna switch behind MMCX connectors make DNMA-H92 the best performance and most feature-rich mini-PCI module valid in the market.
PCI interface, 2mm thickness heat sink, and ath9k driver support ease manufacturer’s design cycles to accelerate time-to-market.

 

 

Key Features

  • High power on both 2.4/5GHz design to reach average power 250mW (24dBm) @ 5GHz and 300 mW (25dBm) @ 2.4GHz provides superior wifi coverage.
  • Integrated 12KV ESD protector on RF port ensures highest levels of performance and reliability in the harshest outdoor mesh/military deployments.
  • 3~5dB Tx linearity improvement than standard MB92 design on all data rate to gain better overall performance.
  • PA damage protection circuit enables direct antenna switch behind MMCX connectors.
  • Dual power supply and heat sink design plus unique design know-how ensure +2.5/-2 dB target power in –20°C ~ +70°C temperature range.
  • 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.
  • 2mm thickness heat sink design provides reliable high power RF performance for embedding into new ergonomic application-specific devices.
  • 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 III A form factor (length is 4.3 mm longer than III A type) with screw hole is ideal for solid mounting onto motherboard.
  • Supported by ath9k providing Linux kernel drivers for industrial, academic, or personal projects at highest flexibility and lowest cost.
  • Linux driver source code sub-license available by project.
  • Dual band 802.11 a/b/g/n support 2Tx/2Rx to enable data rate up to 300Mbps link rate for 40MHz channel, six times the throughput of 802.11a and 802.11g.
  • Supports 64/128/152-bit WEP encryption, IEEE 802.1x authentication, AES and TKIP encryption.
  • Two 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.

Advanced Dual Band 2.4/5GHz High Power WiFi Architecture

Most of high-power mini-PCI modules valid in the market are single band of either 2.4GHz or 5GHz only which are seriously lack flexibility and waste frequency efficiency in real world applications. DNMA-H92 is a real dual-band 2.4/5GHz high power mini-PCI module. Two independent DNMA-H92 modules can be used to form highly flexible and independent high power WiFi connections with both 2.4GHz and 5GHz frequencies to maximize frequency and bandwidth efficiency per application requirement.
