摘要

提出了一种适用于多波段应用的宽带直接转换接收机。该接收机由一个正交下变频器、一个低噪声放大器(LNA)和两个压控振荡器(vco)组成。关键元件集成电路是在砷化镓和硅衬底上制造的。接收器可以接收三个不同的频段，即900mhz频段，1.9 GHz频段和2.4 GHz频段。

A 0.9-2.5 GHz wideband direct conversion receiver for multi-band applications

A wideband direct conversion receiver for multi-band applications is presented. The developed receiver consists of one quadrature downconverter, one low-noise amplifier (LNA), and two voltage-controlled oscillators (VCOs). The key component ICs are fabricated on GaAs and Si substrates. The receiver can receive three different frequency bands, i.e. the 900 MHz band, 1.9 GHz band, and 2.4 GHz band.
