Abstract

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.

First claim

What is claimed is:

1. An apparatus comprising:
a secondary radio frequency integrated circuit (RFIC) coupled to at least a first antenna, the secondary RFIC configured to process analog signals received at the first antenna into an analog output signal; and
a primary RFIC coupled to at least a second antenna, the primary RFIC configured to receive and to further process the analog output signal, the secondary RFIC positioned at a shorter trace length to the first antenna than the primary RFIC.

2. The apparatus of claim 1 , the primary RFIC is coupled to receive signals from at least one additional antenna.

3. The apparatus of claim 1 , the secondary RFIC comprising at least two modules coupled to the first antenna and a third antenna, respectively.

4. The apparatus of claim 3 , at least one module of the at least two modules configured to process the analog signals received from the first antenna to generate the analog output signal.

5. The apparatus of claim 4 , the at least one module configured to at least one of amplify, filter, downconvert, and up-convert.

6. The apparatus of claim 4 , the at least one module comprises a sub-process associated with a process performed by the receiver of the primary RFIC.

7. The apparatus of claim 3 , each module is configured to process at least one of global navigation satellite system (GNSS) signals, wireless wide area network (WWAN) communication signals, Wi-Fi communication signals, and Bluetooth communication signals.

8. The apparatus of claim 3 , each of the at least two antennas is configured to receive signals in at least one of a global navigation satellite system (GNSS) frequency band, a wireless wide area network (WWAN) communication frequency band, a Wi-Fi communication band, and a Bluetooth communication band.

9. The apparatus of claim 3 , the first antenna and the third antenna are configured to receive signals having the same or different frequency.

10. The apparatus of claim 1 , the secondary RFIC positioned within the apparatus to reduce trace loss associated with the analog antenna signals output from the first antenna.

11. The apparatus of claim 1 , wherein the secondary RFIC is configured to process the analog signals received at the first antenna using a sub-process associated with a process performed by the receiver of the primary RFIC, and wherein the primary RFIC is configured to process analog signals received at the second antenna using the sub-process.

12. An apparatus comprising:
a secondary means for processing analog signals received at a first antenna into an analog output signal, the secondary means for processing analog signals located in a secondary radio frequency integrated circuit (RFIC); and
a primary means for further processing the analog output signal and processing analog signals received at a second antenna, the primary means located in a primary RFIC, the secondary RFIC positioned at a shorter trace length to the first antenna than the primary RFIC.

13. The apparatus of claim 12 , the secondary means for processing analog signals comprising at least two modules coupled to the first antenna and a third antenna, respectively.

14. The apparatus of claim 13 , at least one module of the at least two modules configured to process the analog signals received from the first antenna to generate the analog output signal.

15. The apparatus of claim 14 , the at least one module configured to at least one of amplify, filter, downconvert, and up-convert.

16. The apparatus of claim 14 , the at least one module comprises a sub-process associated with a process performed by the secondary means.

17. The apparatus of claim 13 , each module is configured to process at least one of global navigation satellite system (GNSS) signals, wireless wide area network (WWAN) communication signals, Wi-Fi communication signals, and Bluetooth communication signals.

18. The apparatus of claim 13 , each of the first antenna and the third antenna is configured to receive signals in at least one of a global navigation satellite system (GNSS) frequency band, a wireless wide area network (WWAN) communication frequency band, a Wi-Fi communication band, and a Bluetooth communication band.

19. The apparatus of claim 13 , the first antenna and the third antenna are configured to receive signals having the same or different frequency.

20. The apparatus of claim 12 , the secondary means for processing analog signals positioned within the apparatus to reduce trace loss associated with the analog antenna signals received from the first antenna.
