MULTI-FREQUENCY RANGE PROCESSING FOR RF FRONT END

摘要

Techniques for supporting multi-frequency range signal processing for a wireless device. In an aspect, a first antenna is provided to support first and third frequency ranges. A second antenna is separately provided to support two separate ranges that are each intermediate in frequency between the first and third frequency ranges. In an aspect, the two separate ranges may correspond to, e.g., a GPS range and a 1500-MHz band. To separate the two ranges of the second antenna, one or more low-pass and/or band-pass filters may be provided. In other aspects, a third antenna may be added to support a fourth frequency range higher than the third frequency range. Other frequency range combinations, dual antenna aspects, and carrier aggregation features are further disclosed herein.

主权项

1. An apparatus comprising:
a first antenna configured to transmit or receive on a mid-frequency range between two frequency ranges supported by another antenna; and a frequency separation block coupled to the first antenna, the frequency separation block comprising a first frequency-selective section and a second frequency-selective section, wherein the frequency separation block is configured to separate a first sub-range of the mid-frequency range from a second sub-range of the mid-frequency range.
