    摘要： A network interface device includes an active path between an entry port and a first input/output port. The network interface device also includes a passive path between the entry port and a second input/output port. The network interface device also includes a buffer in the active path configured to absorb, attenuate, terminate, or isolate radio-frequency (RF) signals. The network interface device also includes a switching element in the active path configured to selectively bypass the buffer during normal operating conditions.

    摘要： A system having a tunable impedance network and a method of tuning a tunable impedance network are disclosed. In one aspect, a telecommunications device comprises an electrical-balance duplexer (EBD) circuit coupled to at least one output node of a transmit path (TXin), an antenna, and at least one input node of a receive path (RXout), wherein the EBD circuit is configured to isolate the transmit path from the receive path by signal cancellation, and a balancing network (Zbal) as part of the EBD circuit. In one embodiment, the balancing network is an integrated tunable impedance network configured to provide an impedance that matches a target impedance (Zant) associated with the antenna at a first frequency and simultaneously at a second, different frequency. The network comprises a first portion and a second portion, the first portion reducing the influence of the tuning of the second portion at the first frequency. In some embodiments, the network preferably comprises no explicit resistors.

    摘要： A diplexer module includes substrates, an external connection terminal, a first diplexer including a first transmission filter and a first reception filter, a second diplexer including a second transmission filter and a second reception filter, and a switch. The external connection terminal is connected to the switch, the switch is connected to the first diplexer and the second diplexer, and the first transmission filter, the second transmission filter, the second reception filter, and the first reception filter are aligned in this order when the substrates are seen in plan view from above.
