A monolithic RF transceiver for DC-OFDM UWB
摘要
Abstract
This paper presents a first monolithic RF transceiver for DC-OFDM UWB applications.The proposed direct-conversion transceiver integrates all the building blocks including two receiver (Rx) cores,two transmitter (Tx) cores and a dual-carrier frequency synthesizer (DC-FS) as well as a 3-wire serial peripheral interface (SPI) to set the operating status of the transceiver.The ESD-protected chip is fabricated by a TSMC 0.13-μm RF CMOS process with a die size of 4.5 × 3.6 mm2.The measurement results show that the wideband Rx achieves an NF of 5-6.2 dB,a max gain of 76-84 dB with 64-dB variable gain,an in-/out-of-band IIP3 of -6/+4 dBm and an input loss S11 of ＜-10 in all bands.The Tx achieves an LOLRR/IMGRR of-34/-33 dBc,a typical OIP3 of+6 dBm and a maximum output power of -5 dBm.The DC-FS outputs two separate carriers simultaneously with an inter-band hopping time of ＜ 1.2 ns.The full chip consumes a maximum current of 420 mA under a 1.2-V supply.关键词
