[原创] ADI ADRF5020 30GHz RF开关解决方案

ADI公司的ADRF5020是30GHz RF通用单刀双掷(SPDT)和单刀四掷(SP4T)开关,采用 20 引脚和 24 引脚基板栅格阵列(LGA)封装，提供高隔离度和高达30GHz的低插入损耗,超宽带频率范围为100 MHz至30 GHz,非反射式50 Ω设计,低插入损耗2.0 dB(30 GHz时),高隔离度60 dB(30 GHz时),高输入线性度,1 dB压缩(P1dB)28 dBm,三阶交调截点(IP3)52 dBm(典型值),主要用在测试测量,微波无线电和甚小孔径终端(VSAT)以及军用无线电,雷达,电子计数测量(ECM)和宽带通信系统.本文介绍了ADRF5020主要特性和功能框图,以及评估板ADRF5020-EVALZ主要特性,电路图,材料清单和PCB设计图.

The ADRF5020 is a general-purpose, single-pole, double-throw (SPDT) switch manufactured using a silicon process. It comes in a 3 mm × 3 mm, 20-terminal land grid array (LGA) package and provides high isolation and low insertion loss from 100 MHz to 30 GHz.

This broadband switch requires dual supply voltages, +3.3 V and −2.5 V, and provides CMOS/LVTTL logic-compatible control.

The ADRF5020 requires a positive supply voltage applied to the VDD pin and a negative supply voltage applied to the VSS pin. Bypassing capacitors are recommended on the supply lines to minimize RF coupling.
