The center section of the board provides an area for attaching all SMT components to the circuit side and radial leaded components to the component ground side (see Figures 29 and 30). Additionally, the peripheral area surrounding the RF core provides pads to add supporting and interface circuitry as a particular application requires. There is an area dedicated for a LNA preamp. This evaluation board will be discussed and referenced in this section. COMPONENT SELECTION The evaluation PC board is designed to accommodate specif- ic components, while also being versatile enough to use com- ponents from various manufacturers and coil types. The appli- cations circuit schematic (Figure 15) specifies particular com- ponents that were used to achieve the results shown in the typical curves but equivalent components should give similar results. Component placement views are shown in Figures 27 and 28 for the application circuit in Figure 15 and for the 83.616 MHz crystal oscillator circuit in Figure 16. INPUT MATCHING COMPONENTS The input matching circuit shown in the application circuit schematic (Figure 15) is a series L, shunt C single L section which is used to match the mixer input to 50 Ω. An alterna- tive input network may use 1:4 surface mount transformers or BALUNs. The 12 dB SINAD sensitivity using the 1:4 imped- ance transformer is typically –100 dBm for fmod = 1.0 kHz and fdev = ±5.0 kHz at fin = 50 MHz and fLO = 50.455 MHz (see Figure 14). It is desirable to use a SAW filter before the mixer to provide additional selectivity an adjacent channel rejection and improved sensitivity. SAW filters sourced from Toko (Part #SWS083GBWA) and Murata (Part # SAF83.16MA51X) are excellent choices to easily interface with the MC13150 mixer. They are packaged in a 12 pin low profile surface mount ceramic package. The center frequency is 83.161 MHz and the 3.0 dB bandwidth is 30 kHz.
