Coaxial Detector

Coaxial Detector for Broadband Microwave Detection — High Sensitivity & Strong Overload Capacity

The ADM Coaxial Detector is made with point contact diode technology and a wideband matching circuit that was custom made for it. It has good anti-interference performance across a wide range of microwave frequencies, a low standing wave coefficient, a high detecting sensitivity, and a strong overload capacity. This part, which was made by Advanced Microwave Technologies Co., Ltd. (ADM), is designed to work in harsh signal settings like radar, satellite communication, military electronics, and microwave measurement.

What Is a Coaxial Detector?

A product is a microwave signal detector that changes RF energy into a DC or low-frequency signal that can be used. ADM's broadband version has a point contact diode as its main sensing element and a broadband matching circuit that has been carefully tuned to keep performance stable over a wide frequency range.

This design solves one of the most important problems in broadband microwave work: keeping sensitivity and signal integrity without sacrificing impedance matching. The result is a detector that always works, even in places with a lot of electrical noise.

Key Features and Technical Advantages

ADM's product is made for places where there aren't many room for error and efficiency is important.

High Detection Sensitivity

The detector can accurately pick up low-level microwave signals thanks to its point contact diode structure. This is very important for things like radar warning devices and electronic defence systems.

Low Coefficient of Standing Wave

The broadband matching circuit keeps reflections low across the operating band. This keeps measurement accuracy high and protects upstream parts.

Strong Capacity for Overload

The detector can handle signal spikes without permanently losing its performance, so it can be used in places with pulsed radar and for transmission signals that come and go quickly.

High Output Voltage and Anti-Interference Ability

The design makes a clean, usable output even in places with a lot of electromagnetic noise, which is an important quality for military and aerospace equipment.

Product Specifications

Application Scenarios

The broad-band microwave detector is made to work with a variety of professional and military equipment.

Military Electronic Equipment

It is used in radar systems, electronic countermeasure (ECM) gear, and military transmission systems. It works reliably even in complex electromagnetic battlefield conditions thanks to its strong anti-interference performance.

Navigation Systems

In navigation electronics, it's important that signals can be picked up consistently across a range of frequencies. The high sensitivity and low standing wave coefficient make it possible to handle navigation signals steadily.

Microwave Measurement and Test Systems

The coaxial detector from ADM can be used in both lab and field measurement sets. ADM runs a 24-meter Microwave Darkroom testing facility that works from 0.5 GHz to 110 GHz. This is where the performance of detectors is checked against what is needed for real-world measurements.

Satellite Communication and Aerospace

Finding high-frequency signals in satellite uplink/downlink chains and aerospace telemetry systems needs parts that can keep working even when they are put under a lot of stress. The broadband matching design of the device works in these situations.

Quality Control and Testing

An Antenna Plane Near and Far Field Measuring Recombination Chamber is used by ADM to check the performance of a product at different stages of production. This feature allows for flexible near-field and far-field test switching, which lets you fully evaluate signal behaviour.

Key testing checkpoints include:

· Sensitivity verification across the operating frequency band

· Standing wave measurement to confirm low VSWR throughout the broadband range

· Output voltage consistency check under varying input signal levels

· Anti-interference evaluation in simulated high-EMI environments

· Overload capacity testing using pulsed signal inputs to confirm no permanent degradation

ADM has testing equipment that works from 0.5 GHz to 110 GHz, which lets them fully describe broadband radio parts.
