Abstract

The invention discloses a BPSK (binary phase shift keying) modulated UWB (ultra wide band) transmitter radio frequency front-end chip architecture which comprises an ultra wide band pulse generator, a pulse shaper, a first balun, an intermediate frequency amplifier, a second balun, a BPSK modulator, a PLL (phase locked loop) module, a small signal amplifier and a variable gain amplifier. The ultra-wideband pulse generator, the pulse shaper, the first balun, the intermediate frequency amplifier, the second balun and the BPSK modulator are connected in sequence to form a first access used for inputting baseband signals. The PLL module, the small signal amplifier and the BPSK modulator are connected in sequence to form a path II for inputting the clock frequency of the off-chip crystal oscillator; the BPSK modulator integrates and converts a baseband signal and the clock frequency into a UWB signal, and the UWB signal is output after the transmitting power of the output UWB signal is adjusted through the variable gain amplifier; and the power supply management module is used for converting power supply voltage of an external power supply into working voltage required by a module circuit in the chip.

Description

technical field [0001] The invention relates to the field of integrated circuits, in particular to a structure design of a radio frequency front-end chip of a UWB transmitter modulated by BPSK. Background technique [0002] In 2002, the FCC approved the authorization-free use of Ultra Wide Band (UWB, Ultra Wide Band) technology, and IEEE began to add UWB technology to the physical layer standard. The relevant standardization groups include: IEEE802 dedicated to short-distance high-speed wireless personal area network (WPAN). 15.3a standardization working group (hereinafter referred to as 3a working group) and IEEE802.15.4a working group (hereinafter referred to as 4a working group) dedicated to short-distance low-speed WPAN. [0003] The 3a working group could not unify the choice between DS-UWB and MB-OFDM, and then announced that it would abandon the formulation of UWB standards. The standardization process of the 4a working group is richer and more successful. Since the ...
