• Wide operational temperature range supporting industrial environments from -40°C to +85°C
• Integrated tuning voltage input allowing precise frequency adjustment across the specified band

Applications

• Microwave communication systems requiring stable local oscillators
• Frequency synthesis circuits in RF transceivers
• Test and measurement equipment needing precise signal sources

Procurement Notes

Verify the specific ordering suffix against the official Crystek datasheet to ensure compatibility with required packaging or tolerance specifications. Confirm that the application environment remains within the stated -40°C to +85°C thermal limits. Ensure the power supply provides a stable 8 V minimum and that the control voltage stays within the 1 V to 10 V range to prevent damage or erratic behavior during procurement validation.

Selection Notes

Select this component when a fixed frequency range of 1490 MHz to 1550 MHz is required with voltage tuning capabilities. Consider the 8 V supply requirement and the specific tuning voltage window of 1 V to 10 V for circuit design compatibility. Evaluate the -15 dBc typical second harmonic performance against system filtering requirements. Verify that the physical dimensions and mounting style meet the target PCB layout constraints.
