Circuit Description XTAL1 the 40 MHz crystal oscillator provides the base clock source of U3 Wireless LAN network interface controller’s operating. U3 drives reference differential clock for modulator and demodulator of embedded RF transceiver. U3 combines a MAC and 1T1R capable baseband and includes a USB interface for host connection. Embedded RF transceiver consists of one receivers and one transmitters used to form a complete 2.4GHz ISM band Wireless LAN application. Antenna, Ground, and Power Source There is one external 2.4GHz band on-board antenna. Besides Print circuit board provides copper plane ground, host provides a reference grounding connecting by USB interface. Whole system power source is fed with DC 5Volt by USB interface. Tx frequency range: 2412~2462MHz Modulation: CCK, OFDM, QPSK, BPSK, 16-QAM, 64-QAM

RF Exposure Requirements Product Description: Wireless N150 USB Adapter Model No.: ENUWI-1XN42 FCC ID: YZ500000004 Acorrding to the KDB-447498, the following RF exposure evaluation shall to demonstrate RF exposure compliance. Tx frequency range: 2412~2462MHz Antenna-to-tissue separation: <20 cm Antenna Gain: 5dBi Maximum Output Power: 6.59dBm (Conducted) Maximum Output Power: 11.59dBm or 14.42mW (EIRP) Maximum Duty Factor: 100% 60/f(GHz) mW = 24.37 mW Source-based time-averaged conducted output power is 14.42 mW =< 60/f So the transmitter is comply the RF exposure requirements and the SAR in not required.
