Description :

The SG901-1071 Module is a single chip based 802.11b/g/n WLAN radio for embedded, lowpower and extremely small form factor mobile applications. The product conforms to the IEEE 802.11b, g, and n protocols operating in the 2.45GHz ISM frequency band supporting 802.11n modulations up to 72.2Mbps, all OFDM modulations, and all mandatory 802.11b modulations. The SG901-1071 is a fully integrated wireless radio including RF Synthesizer/VCO, high-speed data converters, digital baseband processor, onboard MAC and PHY processors, Power Management, Power Amplifier, and LNA. An on-board EEPROM stores calibration data for alignment-free integration. Bluetooth integration features of the radio are made available. An on-board crystal and filter simplify system integration. Just add one 1.8V regulator, 3.3V Power, Antenna, and host communications.

Description :

The CD7613 is a monolithic integrated circuit designed for the portable AM/FM radio or AM/FM clock radios.

Features :

Portable AM/FM 1-chip radio Wide op erating su pp ly voltage range: Vcc=3V~12V (Approxi mately) (Depending on the internal regulator tolerance) z Recommen ded operating supply voltage : Vcc=4.5V~9V On using AC line as an internal shunt regulator mode , it is transformer (approximately possible to use low cost application without a 42mA). z z IF AMP gain is determined by DC Vo ltage appeared at IC Pin16 Power output: Po=0.28W (Min.) at THD=10% (Vcc=5.5V/8 )
