Why use IAI with +20dBm??
– Extended Range 2000 meters !!!
– Only integrated +20dBm PA available!!!
– Significant cost savings vs. purchasing an external PA
– Highest Efficiency PA available battery life
– Can use low-cost antenna and overcompensate with higher output power to achieve same effective range cost savings
– Automatic ramp-up and ramp-down of PA no spectral splatter
Page 15CONFIDENTIAL

Implications for Using +20dBm
– Different Regulatory Agencies restrict output power in certain bands.
– Most applications will need to implement FHSS to take advantage of +20dBm
• US FCC – Can use +20dBm with FHSS 902-928MHz
• Will need to evaluated on case by case basis for each market
Page 16CONFIDENTIAL
EZRadioPRO
FHSS - Huh??
• What is FHSS? (Frequency Hopping Spread Spectrum)
– Carrier Frequency is changed by pseudo random sequence
– More Resistant to interferers
– Difficult to intercept
– Most importantly allowed to transmit up to +20dBm by FCC!!!
Page 17CONFIDENTIAL
EZRadioPRO
Antenna Diversity
• Advantages of Antenna Diversity – Counters Multi-path Fading and Antenna Polarization
(Some of you may have seen these effects within the EZRadio product line or Competitor chips)
– +8-10dB Gain in Link Budget for typical system
– Algorithm completely integrated – No competitor has this feature
(Very cumbersome and time consuming to do over the SPI with a microcontroller)
Page 18CONFIDENTIAL
EZRadioPRO
What is Antenna Diversity?
• Two antennas in system• EZRadioPRO will choose the best antenna for optimal performance• Gain 8-10dB in Link Budget Gain• Common feature used in cell/cordless phones to avoid multipath/fading
Page 19CONFIDENTIAL
EZRadioPRO
What is the Packet Handler??
• Typical Packet Structure Shown Above
• Preamble, Sync Word TX Header, Packet Length, and CRC fields set through SPI registers
• ALL that needs to be loaded into FIFO is “Data”
• EZRadioPRO will automatically construct/deconstruct the packet
