Abstract: Apparatus and methods for radio frequency (RF) signal limiting are provided. In certain embodiments, an RF signal limiting system includes a cascade of a front limiter and a biased limiter. Additionally, the front limiter provides an initial amount of limiting to an RF signal, while the biased limiter serves to further limit the RF signal. The biased limiter is adaptively biased such that the amount of limiting provided to the RF signal increases in response to an increase in the RF signal level. Such an RF signal limiting system can be used in a variety of applications, including protecting an input of a low noise amplifier (LNA).

Abstract: An integrated circuit (IC) die is disclosed. The IC die can include a signal via extending through the IC die. The IC die can include a transmission line extending laterally within the IC die in a direction non-parallel to the signal via, the transmission line configured to transfer an electrical signal to the signal via. The IC die can include a matching circuit disposed between the transmission line and the signal via. The matching circuit can include inductance and capacitance matching circuitry to compensate for parasitic inductance and capacitance introduced by transition from the IC die to an underlying carrier.

Abstract: Wideband baluns with enhanced amplitude and phase balance are provided. The wideband balun includes a first transmission line connected between a first port and a third port, and a second transmission line connected between a second port and a fourth port, and a third transmission line connected between the third port and a reference voltage, such as ground. To enhance phase and/or amplitude balance of the wideband balun, the wideband balun further includes a compensation structure operable to provide at least one of capacitive compensation or inductive compensation to balance the wideband balun. For example, in certain implementations, the compensation structure includes at least one of (i) a capacitor connected between the first port and the second port or (ii) a fourth transmission line connected between the first transmission line and the third port.
