Abstract: Attenuators having phase shift and gain compensation circuits. In some embodiments, a radio-frequency (RF) attenuator circuit can include one or more attenuation blocks arranged in series between an input node and an output node, with each attenuation block including a local bypass path. The RF attenuator circuit can further include a global bypass path implemented between the input node and the output node. The RF attenuator circuit can further include a phase compensation circuit configured to compensate for an off-capacitance effect associated with at least one of the global bypass path and the one or more local bypass paths.

Abstract: Radio frequency (RF) amplifiers with capacitance neutralization are provided. In certain embodiments, an RF amplifier includes an RF input terminal, an RF output terminal, a gain transistor including a control terminal that receives an RF signal from the RF input terminal, a cascode transistor connected in series with the gain transistor and that provides an amplified RF signal to the RF output terminal, and a neutralization capacitor connected in parallel with the cascode transistor.

Abstract: Disclosed herein are signal amplifiers that include a plurality of switchable amplifier architectures so that particular gain modes can use dedicated amplifier architectures to provide desired characteristics for those gain modes, such as low noise figure or high linearity. The disclosed signal amplifier architectures provide tailored impedances using a degeneration block or matrix without using switches in the degeneration switching block. The disclosed signal amplifier architectures provide a plurality of gain modes where different gain modes use different paths through the amplifier architecture. Switches that are used to select the path through the amplifier architecture also provide targeted impedances in a degeneration block or matrix. The switches that select the gain path are provided in the amplifier architecture and are thus not needed or used in the degeneration block, thereby reducing the size of the package for the amplifier architecture.
