Rev. 0.0.9 3 / 6 4.1 SoC VC3SMP85 uses Ember's EM3585 chip.The chip integrates RF RF and baseband、The MAC hardware、Hardware capture module、ARM® CortexTM-M3 microprocessor、Large capacity Flash and RAM. Therefore, the chip provides users with a low-cost, high-performance ZigBee solutions. 4.2 RF_PA VC3SMP85 have a fully integrated,PA chips. The PA, LNA, Transmit and Receive switching circuitry, the associated matching network, and the harmonic filter all in a CMOS single-chip device. The chip can not only increase the transmission power amplified output signal can also amplify the input signal recep-tion performance enhancement. Not only meet the IEEE802.15.4 / ZigBee all RF functional requirements, but also has a lower cost, is a cost-effective solution for Zigbee RF. PA chips require proper use. The PC5, PC6 should be set ALT_OUT（PUSH/PULL）, Through these two pins to control PA chips, transmit and receive switching channels. In order to improve RF perfor-mance,software should set the EMBER_TX_POWER_MODE_BOOST by emberSetTxPowerMode()（EmberZNet API）,using TX Power Model. In order to avoid damage to the PA chip,during use input power must less than or equal 0dBm. Note ：When generating code using Ember Desktop,EMBER_AF_TX_POWER_MODE of the macro definitionisused to set this parameter.In Desktop configuration options,as follows： Figure 4.2.VC3SMP85 TX Power Mode Configration Options 4.3 Antenna VC3SMP85 default connection board PCB antenna.In order to guarantee the transmission performance, it can not exist around the module ground plane.When using an extenna antenna,you need to pay attention to the antenna lead-out portion of the motherboard design..Ensure the transmission line impedance matching. Avoid the impedance mismatch caused by radio signal reflection, the actual antenna signal power drops, affect the transmission distance.
