摘要
A double balanced diode ring mixer is presented for MB (multiband) UWB (ultra wideband) system. Diode ring mixers are suitable for economical front end of superhetrodyne receivers. Mixer is designed for RF (radio frequency) of 3.35 GHz and IF (Intermediate frequency) of 250 MHz. Proposed mixer is simulated at RF power level ranges from -50 dBm to -20 dBm with a reference RF power level of -42 dBm. Simulation results show conversion loss of 5.022 dB and OIP3 (third order output intercept point) of 4.737 dBm at RF power level of -42 dBm. Mixer effectively suppresses the harmonic and IMD (inter-modulation) products at IF port. Mixer is simulated by using the spice parameters of beam lead schottky diode HSCH-5531 of Avago Technologies, USA.
