Up-conversion module is the core of transmitter, which plays a critical role in millimeter wave communication, radar, guidance and electronic warfare. This paper introduces the design and measurement of a W-band up-conversion module. W-band LO signal is obtained by frequency multiplying, then through up-conversion method, an X-band signal is converted to W-band. By fabricating, assembling and measuring,...
This paper presents the analysis and design of a new W-band pulsed transmitter using injection-locking to achieve pulse-to-pulse coherence and power amplification. First, a new timing scheme is introduced to solve the asynchronous problem that commonly exists in multistage injection-locked transmitters. Then the pulsewidth of one stage in the transmitter is intentionally made somewhat longer than...
A high speed pulse detector at W-band is analyzed and designed based on hybrid integrated technology. The beam lead detector diode HSCH-9161 is adopted. The tested results show that the rising time of the output pulse within 92~98GHz is less than 2~3ns after the modulator and detector when the input modulating pulse signal rise time is 700ps. Due to its fast response speed, this detector can be applied...
In this paper, design of an eighth sub-harmonic (SH) mixer at W-band using microstrip transmission lines is introduced. According to concretely analyzing, another improved eighth SH mixer is designed. The measurement results show that its best conversion loss is about 10 dB less than the first one. In addition, the bandwidth of RF frequency is 10 GHz (90-100 GHz). In addition; the structure of the...
