Abstract :
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.
