    Microwave detector is a device that detects useful information in a fluctuating signal.

    In test and measurement applications, millimeter wave detectors can be used for precise measurement of RF power, as well as as part of the input protection circuit in the spectrum and network analyzer; In communication and medical applications, BroadBand detectors are used to monitor and control transmission power and antenna return loss.
    A coaxial detector is a device based on a coaxial cable structure that can be used to measure the strength of weak radio frequency signals. They are suitable for many applications, such as telecommunications, broadcasting, aviation, and military communication. Its characteristics are high sensitivity, high accuracy, and small size, which can withstand high-power signals; Waveguide detectors are devices based on waveguide structures that can measure high-power radio frequency signals. It is usually used for applications such as high-power radar and microwave heaters. Compared with coaxial detectors, waveguide detectors are not as sensitive as the latter, but have the characteristics of fast response and high power tolerance.
    Our radio frequency detectors are divided into coaxial detectors and waveguide detectors. Coaxial detectors are designed for low-power applications, while waveguide detectors are designed for high-power applications.

    Qualwave Inc. supplies rf detectors work from DC to 110GHz. The frequency range of the coaxial detector is 0.01GHz~110GHz, with two polarity of Negative, Positive. The input connector type is SMA(m), N(m), 2.92mm(f), 2.4mm(f), 1.85mm(f), 1.0mm(f) and the output connector type is SMA(f), N(f), BNC(f), 2.92mm(f).
    The frequency range of the waveguide detector is 26.5GHz to 325GHz, the maximum flatness is ±2.2dB, the polarity are Negative and Positive, the input connector type is waveguide port, and the output connector type is SMA(f).
    Our high sensitivity detectors are widely used in many applications. Welcome customers to negotiate the choose and buy.
