Table 4. SKY42068 Electrical Specifications Note 1: In a 50 Ω system obtained with external matching components on input/output ports. Note 2: Include RF balun and IF transformer losses. Note 3: Measured with an RF input power of –10 dBm. Note 4: Measured with an RF input power of –16 dBm. Note 5: Use high side LO injection for RF frequencies below 500 MHz. Board layout. The Bill of Materials (BOM) is provided in Table 5.
- Paths to ground should be made as short as possible.
- The ground pad of the SKY42068 mixer has special electrical
board. Multiple vias to the grounding layer are required.
- Two external output bypass capacitors are required on the VDD
- The RF input must be driven differentially. A 1:1 impedance
side that is a DC path to ground.
- Connect the SKY42068 Evaluation Board (J1) to a +5 VDC
