应用于Ka波段无线通信的发射前端模块设计与制造
Design and manufacture of transmitting front-end module for wireless communication in Ka-band
摘要
Abstract
A transmitting front-end module for wireless communication in Ka-band is introduced,which is composed of the frequency mixer,microstrip filter,voltage-controlled oscillator(VCO),frequency multiplier and power amplifier. When the RF signals work at 27.4~28 GHz,the intermediate-frequency signal is fixed in 1 GHz. The simulation results show that the gain of the transmitting front-end is more than 10 dB,the transmitting power is 11.823 dBm,and the intermodulation signal is sup-pressed below 63 dBc while the signal works within the working frequency band. When all chips are working,the temperature simulation result show that the junction temperature of the chip is below 64 ℃. The test results show that,when the signal works within the working frequency,the insertion loss of the signal line in output terminal is less than 0.34 dB,the return loss is less than -20 dB,and the VCO output power after 8 frequency division is -10.66 dBm.关键词
