D602 SiGe Semiconductor, D602 Datasheet - Page 6

• Manufacturer Part Number: D602
• Description: 3V, 6GHz Divide-by-2 Static Prescaler
• Manufacturer: SiGe Semiconductor

Typical Applications Information
* The 47k resistor provides a DC offset that disables self oscillation in the absence of an RF input.
Cascading D602 Prescales
D602 prescalers can be cascaded to achieve division ratios other than 2. For example two D602 prescalers
can be used as shown in the following diagram to perform frequency division by 4.
