7.2.1.1 Design Requirements

Key design requirements for a multiband receive applications is to optimize NF, gain, and S11 to the frequency range of interest. Choose the input matching network for the Figure 6-3 to support a frequency range of 1165MHz to ≈1630MHz that covers all the major upper and lower GNSS L-bands. The S22 of TRF3302-Q1 is inherently wideband and less than –10dB from 1200MHz to beyond 1630MHz. Choose an optional output match to achieve an output return loss (S22) of less than –10dB in the entire frequency range of interest from 1165MHz to 1630MHz.
