6.0 TRC105 Design In Steps
Designing a TRC105 into an application consists of seven steps:
The details of each of these steps are discussed below.
6.1 Determining Frequency Specific Hardware Component Values
6.1.1 SAW Filters and Related Component Values
RFM offers a low-loss SAW RF filter for each of the TRC105’s operating bands listed in Table 57. The part num-
bers for these SAW filters and the values of the related tuning components are referenced to Figure 2. The SAW
filters are designed to take advantage of the TRC105’s differential output to achieve low insertion loss and high
out-of-band rejection.
