A global navigation satellite system receiver with filter bypass mode for improved sensitivity is disclosed. In an aspect, an apparatus is provided that includes a non-bypass signal path coupled to a receiver, the non-bypass signal path comprising a filter. The apparatus also includes a bypass signal path coupled to the receiver, the bypass signal path configure to bypass the filter, and a switch to couple an antenna to the non-bypass signal path during time intervals when signals transmitted by an unrelated local transmitter are transmitted with a signal power that exceeds a selected threshold, and to couple the antenna to the bypass signal path during other time intervals.

An RFIC configuration for reduced antenna trace loss is disclosed. In an exemplary embodiment, an apparatus includes a primary RFIC and a secondary RFIC that is configured to receive analog signals from at least two antennas. The secondary RFIC is configured to process selected analog signals received from at least one antenna to generate an analog output that is input to the primary RFIC.

Techniques for designing a low-noise amplifier (LNA) for operation over a wide range of input power levels. In an exemplary embodiment, a first gain path is provided in parallel with a second gain path. The first gain path includes a differential cascode amplifier with inductor source degeneration. The second gain path includes a differential cascode amplifier without inductor source degeneration. The cascode transistors of the gain paths may be selectively biased to enable or disable the first and/or second gain path. By selectively biasing the cascode transistors and input transistors, various combinations of the first and second gain paths may be selected to provide an optimized gain configuration for any input power level.
