CVCO55BE-2600-3100

Overview

The Crystek CVCO55BE-2600-3100 is a voltage-controlled oscillator (VCO) designed for microwave applications. It operates within a frequency range of 2600 MHz to 3100 MHz and utilizes a QFN-16 surface-mount package measuring 12.70 x 12.70 mm with a height of 3.81 mm. The device requires a 5V supply voltage and draws approximately 25 mA of operating current. Key electrical specifications include a tuning sensitivity of 4 MHz/V, a phase noise of -100 dBc/Hz at 1 kHz offset, and an output power of 4 ± 2 dBm. Secondary harmonic suppression is rated at -15 dBc. The component supports a control voltage range of 1 V to 17 V and functions reliably across an industrial temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific part number suffix against official Crystek documentation to ensure correct frequency range and pinout configuration. Confirm RoHS compliance status through manufacturer datasheets prior to integration. Validate thermal management requirements for the QFN-16 package based on system power dissipation limits. Ensure supply voltage regulation meets the 5V specification to maintain stable oscillation parameters.

Selection Notes

Select this component when a wide tuning range between 2600 MHz and 3100 MHz is required with low phase noise characteristics. Consider the QFN-16 footprint for space-constrained PCB layouts requiring surface-mount technology. Evaluate the 4 MHz/V tuning sensitivity against system modulation bandwidth requirements. Assess the -15 dBc secondary harmonic level for spectral purity needs in adjacent channel applications.
