15196 基于Ga As p HEMT工艺设计了一款2.3~2.7 GHz双模式低噪声射频接收前端全集成芯片。 A fully-integrated dual-mode low-noise RF receiver front-end for the 2. 3 GHz 2. 7 GHz band was presented based on a GaAs pHEMT technology.
15197 该接收前端芯片包含一个单刀双掷(SPDT)收发开关及一个带旁路功能的低噪声放大器。 The receiver front-end consists of a single-pole double-throw( SPDT) transmit-receive switch and a low-noise amplifier( LNA) with bypass mode.
15198 一方面,采用带源级电感负反馈的共源共栅结构实现了放大器模式,将SPDT开关作为放大器输入匹配网络的一部分,一体化优化设计获得最少元件及较高Q值的输入匹配网络,进而实现低噪声、高增益和良好的输入回波损耗匹配; The cascode common-source structure with inductive degeneration topology is adopted to achieve the LNA. The SPDT switch is embedded into the input matching network as a concurrent design to realize high Q matching network with minimum components for low noise, high gain and superior input return loss matching.

15200 测试结果表明,在2.3~2.7 GHz的宽频带范围内,实现的接收前端芯片在LNA模式下的噪声系数可达到1.53~1.64 d B的较低水平,且增益在18.1~19.2 d B之间,在2.5 GHz时输入1 d B压缩点为-1.5 d Bm; The measurement results show that the presented FEM exhibits low noise figure of 1. 53 1. 64 dB and gain of 18. 1 19. 2 dB for 2. 3 2. 7 GHz frequency range in the high-gain LNA mode. At 2. 5 GHz, the tested input 1 dB compression point at 2. 5 GHz is-1. 5 dBm.
15201 在旁路模式下,插入损耗在工作频段内维持在约6~7 d B的水平。 The insertion loss in Bypass mode typically varies from 6 to 7 dB in the operation frequency bands.
15202 利用锁相环与多次倍频的方式设计了一个Ka波段的用于小型化交会参数探测单元的频率源。 In this paper, a Ka-band frequency source for miniaturization of rendezvous parameter detection unit is designed by us-ing PLL and multiple frequency multiplication.
15203 该频率源输出频率为36 GHz,输出功率大于15 dBm。 The output frequency of the frequency source is 36 GHz and the output power is higher than 15 dBm.
15204 在设计时使用数学建模的方法对锁相环各个部分进行建模,然后得到系统的传递函数,通过对闭环系统的系统函数分析,得到能够使系统稳定工作的系统参数。 In this design, the mathematical modeling method is used to model each part of the PLL, and then the trans-fer function of the system is obtained. Through the analysis of the system function of the closed-loop system, the system parameters that can make the system work stably are obtained.
