In this paper, We proposed a broadband RF amplifier for Microwave band receiver. We also proposed a broadband RF amplifier, designed by using EM simulation for reliable amplification of the received signal. Connected to a source terminal to via, it minimizes those which are the active elements of source-side oscillation as the operating element in an ideal GND, and a constant gain characteristic in a broadband. The goal of this was to obtain stable amplification characteristics. For implementing this architecture, we designed the broadband(500 MHz ∼ 7 GHz) RF amplifier by using commercial GaAs FET, which operate on 720 MHz, 4,595 MHz, and 6,035 MHz by impedance matching. The voltage gain is 10.635 dB ∼ 14.407 dB(737.5 MHz ∼ 6.0575 GHz), P1dB is 20 dBc of band(1st harmonic/2nd harmonic)

본 논문은 다중 대역 레이더 수신기의 소형화를 위한 이중 모드 주파수 혼합기를 구현하였다. 제안한 혼합기 는 역병렬 다이오드(anti-parallel diode)를 이용하였고, 제어 전압 유무에 따라 기본파 혼합기 또는 부고조파 혼합 기로 동작한다. 제어 전압을 인가하여 기본파 혼합기로 동작하는 경우, X-대역에서 -10 dB 변환 손실, 2.0 dBm P1dB 특성을 나타내었고, 제어 전압을 인가하지 않은 부고조파 혼합기로 동작하는 경우 K-대역에서 -10 dB 변환 손실, 2.0 dBm P1dB 특성을 나타내었다. AbstractIn this paper, we propose a dual-mode mixer to have multi-band radar signal receiver to be compact. The proposed mixer using a anti-parallel diode is operated as a fundamental mixer or sub-harmonic mixer with respect to a control voltage. A fundamental mixer with a control voltage show a conversion loss of -10 dB, 1dB compression point of 2 dBm at X-band. On the other hand, it is performed as a sub-harmonic mixer with a conversion loss of -10 dB, 1 dB compression point of 2 dBm at K-band.
