A cable network system for bidirectionally communicating signals at an enhanced duplex frequency range, which may be between about 5 MHz and about 650 MHz. This system may include a first amplifier, which may be configured to condition an upstream signal proceeding from a subscriber premises to a headend, without necessarily conditioning a downstream signal proceeding from the headend to the subscriber premises, a second amplifier, which may be configured to condition the downstream signal without necessarily conditioning the upstream signal, and a shaping circuit, which may condition the upstream and downstream signals. This system also may simultaneously, or in an overlapping or offset manner, communicate signals at a full duplex frequency range without a diplex filter.

An apparatus for wireless communications includes a power amplifier, a low-noise amplifier, a power detector, and a transformer. The transformer includes a first inductor coupled to an output of the power amplifier, and a second inductor coupled to an antenna, wherein the second inductor is magnetically coupled with the first inductor. The transformer also includes a third inductor coupled to an input of the low-noise amplifier, wherein the third inductor is magnetically coupled with the second inductor. The transformer also includes a coupling inductor coupled to an input of the power detector, wherein the coupling inductor is magnetically coupled with at least one of the first inductor and the second inductor.

A radio frequency integrated circuit (RFIC), including a power amplifier (PA) connected to an antenna through a first electromagnetic (EM) element, the PA configured to receive a transmit signal from a second EM element, a low noise amplifier (LNA) connected to the first EM element and the second EM element, the power amplifier and the LNA comprising separate amplifier cores, and wherein the first EM element comprises a first plurality of interwound windings occupying a first common area and the second EM element comprises a second plurality of interwound windings occupying a second common area.

Embodiments describe systems, apparatuses, and methods for transmitting/receiving signal data to/from a plurality of transceiver modules. Devices in accordance with some embodiments can include a plurality of wireless transceiver modules, each wireless transceiver module to be communicatively coupled to a corresponding external transceiver module, one or more antennas to exchange signal data with the plurality of external transceiver modules, a radio frequency (RF) circulator, and one or more amplifiers to amplify the signal data received by the one or more antennas and signal data to be transmitted by the one or more antennas. The use of the RF circulator prevents transmitting signals that may collide with each other and cause interference with the communications.

In one embodiment, a method receives a downstream signal and an upstream signal in a same frequency band. The downstream signal and the upstream signal are separated into a first path and a second path. The downstream signal using the first path and the upstream signal using the second path are amplified in an analog domain. The method isolates the downstream signal and the upstream signal from one another and sends the downstream signal downstream to a subscriber device and sends the upstream signal towards a full duplex node.
