Table 1. Electrical Specifications @ +25°C, VDD = 3.0 V - 5.0 V Notes: 1. Device Linearity will begin to degrade below 5 MHz.
- Note Absolute Maximum in Table 4.
- See Figures 12 and 13 for typical attenuation error.
- Measurements made in a 50 ohm system (see Figure 4, Test Circuit Block Diagram). Resistors (R2, R3, R5, R6, R7) with a
value of 10K-ohm are used to decouple the RF path from the control inputs. Figure 2. Package Type
