PE8509

Overview

The PE8509 is an SMA calibrated noise source module manufactured by Pasternack. It operates within a frequency range of 12 GHz to 18 GHz and provides a nominal Excess Noise Ratio (ENR) of 30.0 dB with a tolerance of ±1 dB. The device requires a +28 VDC power supply and features an SMA female input connector paired with an SMA male output connector. Designed for 50 Ohm impedance systems, it exhibits a voltage sensitivity of 0.1 dB/%V.

Feature Summary

• Provides high-output calibrated noise generation for RF testing applications
• Features SMA male-to-female interface configuration for system integration
• Operates on a standard +28 VDC power supply requirement

Applications

• Receiver sensitivity testing
• Noise figure measurement systems
• RF component characterization

Procurement Notes

Verify the specific ENR value required for your application, as documentation references both 26 dB and 30.0 dB specifications for this model. Confirm that the +28 VDC power supply matches your test setup capabilities. Ensure the SMA female-to-male connector orientation aligns with your signal chain requirements before finalizing procurement orders.

Selection Notes

Select this module when a broadband noise source covering the 12 GHz to 18 GHz range is necessary. The unit is suitable for applications requiring a stable noise output with defined voltage sensitivity characteristics. Consider the physical connector types and DC power requirements when designing the surrounding test infrastructure.
