1. Outline Wireless audio transmitter & receiver that use 2.4GHz wide banded, frequency range is 2402MHz~248 MHz, transmitter output is 0dBm, i.e. 1mW. This has 15MHz of frequency hopping extent per one channel. 2. Schematic flow chart - transmitter 2.1 Microphone (condensor microphone) It is input section to be inputed audio signal. It’s operating voltage is 1.5V~3.0V, and makes microphone act by supplying 2.2V. 2.2 CODEC It supplies Mic Bias voltage (from input section) and converts inputed signal into ADC (analog digital converting) and do sampling 2.4KHz. 2.3 CPU It detects voltage of internal bettery and codec's various functions. Also, controls NRF2401AG RF IC (made by Nordic company) and WM8731LEF/R IC (made by CODEC Wolfson). 2.4 LED DISPLAY After sending voltage data (from voltage detect section) to CPU, controls LED display by using data transfered. Also, send fairing data sended from NRF2401AG RF IC (made by Nordic company) to CPU, controls LED display by using data transferred. 2.5 MODEM Data (from Mic input section) is inputted into CODEC, and digital ADC data (inputted into CPU) is transffered to internal antena through RF IC and then data is transffered to fixed frequency. 3. Schematic flow chart -Receiver 3.1 Internal antena Receives transmited frequency and transmits to MODEM. 3.2 MODEM Transmits data received by antena to CPU. 3.3 CPU Transmits data (received by MODEM) to CODEC and controls surrounding various circuit. 3.4 CODEC It does DAC (Digital analog converting) by using received data from CPU, transfer audio data (inputted from Wire Mic & Audio External Input) to CPU or Amplifier section. 3.5 Volume UP/DOWN KEY Data (produced by controling key) is transferred into CPU, CPU controls LCD DISPLAY circuit and signal gain of CODEC. 3.6 AMP Amplifiers audio signal (inputted from CODEC) and runs speaker. It is fixed gain method and analog BTL alplifier, not digital amplifier. 4. Internal Battery 4.1 Tranmitter battry Transmitter battery is a Rithium polymer battery, which has 3.3V ~4.2V voltage range and 240mAh of capacity. It's charging fills up 120mAh per hour and external chrger is equiped with CPU. Current consumption value is 3.5mAh per hour. 4.2 Receiver battery Receiver batteries are connected in serial, have 6.6V ~ 8.4V of voltage range , 2000mAh capacity. External charger is equipped with CPU, chrging fills up 800mAh per hour. Current consumtion value is 200mAh per hour.

Measurement & Results 3.1 ANTENNA REQUIREMENT 3.1.1 Regulation According to §15.203, an intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this Section. The manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is prohibited. And according to §15.247(b)(4), the conducted output power limit specified in paragraph (b) of this section is based on the use of antennas with directional gains that do not exceed 6 dBi. Except as shown in paragraph (c) of this section, if transmitting antennas of directional gain greater than 6 dBi are used, the conducted output power from the intentional radiator shall be reduced below the stated values in paragraphs (b)(1), (b)(2), and (b)(3) of this section, as appropriate, by the amount in dB that the directional gain of the antenna exceeds 6 dBi. 3.1.2 Result :PASS The transmitter has an integral Chip antenna. The directional gain of the antenna is 2.0 dBi. Report Number : KSQ-FCC091218F…
