Dual-mode radio frequency transceiver switch

The embodiment of the invention provides a dual-mode radio frequency transceiver switch. The dual-mode radio frequency transceiver switch comprises a first radio frequency port TX_OUT, a second radiofrequency port TX_IN, a third radio frequency port RITO, a fourth radio frequency port RX_IN, a fifth radio frequency port RX_OUT, a first transmission line TL1, a second transmission line TL2, a first NMOS tube M1, a second NMOS tube M2, a third NMOS tube M3, a fourth NMOS tube M4 and a fifth NMOS tube M5. The dual-mode radio frequency transceiver switch can work in multiple modes, and is low inloss, low in cost, high in isolation degree and high in linearity. 本公开的实施例提供了双模式射频收发开关。所述双模式射频收发开关包括第一射频端口TX_OUT、第二射频端口TX_IN、第三射频端口RITO、第四射频端口RX_IN、第五射频端口RX_OUT、第一传输线TL1、第二传输线TL2、第一NMOS管M1、第二NMOS管M2、第三NMOS管M3、第四NMOS管M4、第五NMOS管M5。所述双模式射频收发开关可工作于多种模式、低损耗、低成本、高隔离度、高线性度。
