| Abstract |
This paper describes the Dual-band WLAN transmitter with 2.4[㎓]와 5[㎓]. Dual-band WLAN transmitter was designed at 2.4[㎓] and 5[㎓]. The Dual-band WLAN transmitter has a amplifier which operate at 2.4[㎓] and 5[㎓] frequency and two VCO(Voltage Controlled Oscillator) or VCO has a wide scope of frequency. these problem cause a size and a power consumption, The Dual-band WLAN transmitter module was proposed to solve these. the transmitter was designed to get output signals of IEEE 802.l1a"s 5.8[㎓] band signal using frequency multiplication way or to act a amplifier about the 2.4[㎓] band signal of IEEE 802.l1b/g, according to inputed frequency and bias voltage that approve using single transmission block. The output spectrum get the improved specification of ACPR of 4[㏈], 6[㏈], 16[㏈] at + 11[㎒], +20[㎒], +30[㎒] offset of center frequency compared to no linearization, was satisfied to transmit spectrum mask of IEEE 802.l1a wireless Lan. |
