High-Linearity Biased Schottky Detector (1 GHz to 2 GHz)

Service Description

End Product

This high-performance sensing component is a biased Schottky detector engineered to deliver an exceptionally consistent frequency response across a wide 1 GHz to 2 GHz range. The device utilizes negative video output polarity and functions efficiently without the requirement of an external DC power source. Its architecture includes 50 ohm matched inputs and provides a high typical voltage sensitivity of 2000 mV/mW, specifically designed for the identification of extremely faint signals. Furthermore, it is built to endure continuous wave (CW) input power levels reaching up to +23 dBm.

The unit is housed in a rugged and compact cylindrical enclosure, featuring an SMA male input connector and an SMA female output connector. This design is optimized for precision test and measurement, instrumentation, and advanced subsystem integration.

Technical Specifications

• Frequency Spectrum: 1000 MHz – 2 GHz
• Response Flatness: ±0.25 dB
• Max Input Capacity: +23 dBm
• Operational Temperature: -55°C to +125°C

Operational Note: Performance metrics are recorded at +25°C with a 100uA bias and -20 dBm input. Voltage sensitivity is calculated as an open circuit value, while TSS is determined using a 2 MHz video bandwidth alongside a 2 dB noise figure amplifier.

Physical and Environmental Characteristics

• Size: 1.23 inches (31.24 mm) in length and 0.314 inches (7.98 mm) in width.
• Weight: 0.0215 lbs (9.75 g).
• Thermal Tolerance: Operational from -55°C to +125°C; storage capable from -65°C to +150°C.
• Connectors: Equipped with an SMA male input and an SMA female output for seamless integration.

Typical Applications

This robust sensor is ideal for high-reliability environments, including radar technology, electronic warfare, and military communication systems. It is also extensively used for AM noise profiling, monitoring systems, and performing high-accuracy measurements in ultra-broadband pulsed RF applications.
