    摘要： The present disclosure provides an apparatus that includes a first mixer circuit configured to convert between an RF signal and an IF signal based at least in part on an local oscillator (LO) signal. The first mixer circuit is electrically coupled to a first node that is configured to receive the LO signal and a first bias voltage, a second node that is configured to receive the RF signal or the IF signal, and a third node that is configured to provide the IF signal or the RF signal. The apparatus further includes a second mixer circuit electrically coupled to a fourth node configured to receive the LO signal and a second bias voltage, the second node, and the third node. The second bias voltage has a voltage level that is offset from the first bias voltage.

    摘要： Aspects described herein include devices and methods with chain routing of signals for massive antenna arrays. In some aspects, an apparatus is provided that includes a first millimeter wave (mmW) transceiver having a first port, a second port, one or more antenna elements, a plurality of chain mmW transceiver ports, and switching circuitry. The switching circuitry is controllable by control data to route portions of a merged clock and data signal and a merged control and data signal between a first route between the one or more antenna elements and the first port and a second route between the one or more antenna elements and the second port and a third route between the first port and the plurality of chain mmW transceiver ports and a fourth route between the second port and the plurality of chain mmW transceiver ports.

    摘要： Receiver circuits that can be reconfigured to generate test signals in a wireless device are disclosed. In an exemplary design, an apparatus includes a mixer and an amplifier. The mixer downconverts an input radio frequency (RF) signal based on a local oscillator (LO) signal in a first mode. The amplifier, which is formed by at least a portion of the mixer, amplifies the LO signal and provides an amplified LO signal in a second mode. In another exemplary design, an apparatus includes an amplifier and an attenuator. The amplifier receives and amplifies an input RF signal in a first mode. The attenuator, which is formed by at least a portion of the amplifier, receives and passes an LO signal in a second mode.
