摘要: This paper presents a highly-integrated 3-8 GHz ultra-wideband (UWB) RF transmitter implemented in 1.2 V 0.13m CMOS technology. The integrates an analog baseband (PGAs and filter), IQ modulator, variable gain amplifier (VGA), differential-to-single-ended amplifier, power as well transmitted signal strength indicator (TSSI). VGA the TSSI cooperate to perform automatic transmit control. modulator off-chip digital circuit by FPGA carrier leakage calibration. Measured maximum output OP1 dB are -5 +1.5 dBm, respectively. worst suppression is 21 (before calibration) at 6.6 GHz. sideband 29.1 7.6 high linearity accurate modulation lead error vector magnitude (EVM) of -28 under data rate 480 Mb/s WiMedia Mode 1. entire consumes 66 mW supply voltage V.
