Overview
The RQRA-0400-0800 is a Voltage Controlled Oscillator (VCO) manufactured by Raltron Electronics. It operates within a frequency range of 400 MHz to 800 MHz, with a center frequency of 600 MHz. The device utilizes a control voltage input ranging from 0 V to 12 V. It delivers an output power of approximately ±5 dBm and exhibits a typical second harmonic level of -5 dBc. The component is packaged in a surface-mount 16-QFN variant with dimensions of 0.500 inches by 0.500 inches.
Feature Summary
- Voltage-controlled operation across a 400 MHz to 800 MHz frequency band
- Surface-mount QFN package design for compact integration
- Control voltage input range supporting 0 V to 12 V modulation
Applications
- RF signal generation circuits
- Frequency synthesis systems
- Wireless communication transceivers
Procurement Notes
Verify the specific datasheet version and manufacturer documentation before procurement. Confirm that the 16-QFN package dimensions and pinout match the target PCB layout. Ensure the control voltage requirements align with the system's available bias supplies. Cross-reference the part number with authorized distributors to confirm current availability and authenticity.
Selection Notes
Select this component when a wide tuning range between 400 MHz and 800 MHz is required. Consider the 0 V to 12 V control voltage span for compatibility with existing driver circuits. Evaluate the ±5 dBm output power against downstream amplifier needs. Assess the SMD form factor for space-constrained designs requiring robust RF performance.
Part Context
This model belongs to the RQRA series of Voltage Controlled Oscillators from Raltron Electronics. The series includes variants covering different frequency bands, such as the RQRA-0060-0110 for lower frequencies and the RQRA-1480-1600 for higher ranges. All models share similar physical packaging characteristics.
Replacement Considerations
The CVCO55BE-0400-0800 from Crystek Corporation is a comparable alternative offering similar frequency coverage. Verify mechanical footprint differences, as the Crystek variant uses a 12.7x12.7 mm package compared to the 0.5x0.5 inch size of the Raltron part.
