On Lmds On Converting And Receiving Components Developed

The thesis is a part of 'LMDS' millimeter-wave. The purpose is to escalate 30GHz signals to 35GHz and attain 14dB conversion gain by means of power amplifier.In passive section, Above all, I introduce theory about microstrip line. Millimeter-wave band-pass filter and wave guide-to-microstrip transition. Designing two type of coverer by image-reject mixer and HMC329. In former, image-reject mixer uses phasing to differentiate between two single-balance mixers. It's four diode is type of DMK-2606 by made Alphar Corporation, module of mixer's integrated circuit is simulate by senerade 8.0 and ADS software. The latter, upcoverer is fabricated by using HMC329. At last, millimeter wave band-pass filter is also simulating by senerade 8.0 and ADS software.In active section, in order to meet performance of out put power above 10dBm, the power amplifier module of Ka-Band is fabricated by using HMC283 to achieve the 14dB conversion gain.There are five parts that include of waveguide-to-microstrip﹑mixer﹑filter﹑power Amplifier and waveguide-to-microstrip. Input signal's power is 10dBm, after it pass waveguide-to-microstrip, it's frequency is escalate from 30GHz to 35GHz. Through mixer and filter others frequency by millimeter wave band-pass filter.In order to compensate for conversion loss of waveguide-to-microstrip transition. Mixer and filter, adding a power Amplifier by using HMC283 to achieve 14dB conversion gain.As a result, through testing module of upcoverer-Amplifier, the module can meet performance of 'LMDS' millimeter wave frontend. As a key component of the radio system. Assembly module of upcoverer-Amplifier have advantage of small volume﹑ low-cost and reliable. So it can improve the performance of the whole system.
