摘要
采用0.25 μ m BiCMOS工艺实现了一种用于MB-OFDM UWB的11波段3.4-10.3GHz直接转换接收机。它包括一个5.25GHz抗干扰的射频前端，一个产生11个快速跳频正交载波音的频率合成器，以及一个具有42dB增益可编程性的线性相位基带部分。安装在FR-4基板上的封装IC在所有频段上提供67-78dB的最大增益和5-10dB的NF，同时从2.5V电源消耗114mA
An 11-Band 3.4 to 10.3 GHz MB-OFDM UWB Receiver in 0.25/spl mu/m SiGe BiCMOS
An 11-band 3.4-10.3GHz direct conversion receiver for MB-OFDM UWB is implemented in a 0.25mum BiCMOS process. It includes an RF front-end with interference rejection at 5.25GHz, a frequency synthesizer generating 11 carrier tones in quadrature with fast hopping, and a linear phase baseband section with 42dB of gain programmability. The packaged IC mounted on FR-4 substrate provides maximum gain of 67-78dB and NF of 5-10dB across all bands while consuming 114mA from a 2.5V supply
