Power Detector – 50 MHz to 5 GHz

Service Description

End Product + Design Documents + Production Documents

This RF power detector is designed with SMA female input and output connectors and operates over a frequency range of 50 MHz to 5 GHz. It supports a maximum input power level of 0 dBm, making it suitable for low-power signal detection in various RF applications.

Housed in a compact coaxial design, this detector is ideal for monitoring and measuring signal strength in communication systems, test setups, and laboratory environments. Its wide frequency coverage and standard SMA interface ensure compatibility with a broad range of RF equipment.

This broadband RF power detector module operates across a wide frequency range from 50 MHz to 5 GHz. It delivers a true RMS response with a positive output voltage slope ranging from 0.1 to 5 volts, offering a dynamic range of 30 dB. The module also features a fast pulse response time, typically around 7 microseconds.

Designed for 50 Ohm systems, the detector requires only a single +5V DC power supply and can accommodate input power levels up to +15 dBm. It uses female SMA connectors for easy integration with standard RF equipment.

Built into a durable and compact housing, the detector is engineered for reliability in harsh conditions. It supports operation over a temperature range of -40°C to +85°C and complies with MIL-STD-202 standards for resistance to humidity, shock, vibration, and altitude—making it suitable for both commercial and military-grade applications.
