Analog Devices Inc. HMC7992 非反射式硅 SP4T 开关
Analog Devices HMC7992 非反射式硅单刀四掷 (SP4T) 开关非常适合用于蜂窝基础设施应用。 HMC7992 开关具有 45dB 的高隔离和 2GHz 时的 0.6dB 低插入损耗。 HMC7992 具有高达 6GHz 的出色功率处理能力，5V 时 35dBm 的输入功率为 1dB 压缩点 (P1dB)。这些开关显示出低于 0.1GHz 的良好低频输入功率处理能力。 HMC7992 开关在 21dBm 典型 1dB 压缩时运行可低至 10kHz，在 1MHz 时 37dBm 为 IIP3。 HMC7992 的片上电路使该开关能够使用 3.3-5V 正极控制单电源以及 0-1.8/3.3/5V 正极控制单电压运行。HMC7992 的集成式 2:4 解码器只需要两个受控输入信号，正极控制电压范围为 0-1.8/3.3/5V。2:4 解码器可以让设计人员从四个射频 (RF) 路径中选择一个。
The HMC7992 switches provide high isolation of 45dB and a low insertion loss of 0.6dB at 2GHz. HMC7992 delivers excellent power handling up to 6GHz with input power of 1dB compression point (P1dB) of 35dBm at 5V. The switches exhibit good, low-frequency input power handling below 0.1GHz. The HMC7992 switches can operate as low as 10kHz with a typical 1dB compression of 21dBm, and an IIP3 of 37dBm at 1MHz. HMC7992's on-chip circuitry enables the switch to operate using a single, positive 3.3-5V supply voltage as well as a single, positive-control voltage from 0-1.8/3.3/5V.
HMC7992 integrated 2:4 decoder needs only two controlled input signals with a positive-control voltage range from 0-1.8/3.3/5V. The 2:4 decoder allows the designer to select one of the four radio frequency (RF) paths.
