Outline Drawing of K2.92 Series Female 2-hole Flange Stainless Steel RF Coaxial Connector(mm):

Features:
- Compatibility:
- Intermateability: it can be interchangeably mated with SMA and 3.5mm connectors, which increases its flexibility and convenience in practical applications. For example, when the corresponding connector is temporarily unavailable, accessories such as adapters can be used to interconnect different series of connectors.
- Other features:
- Air medium: adopting air as the transmission medium draws on the advantages of air transmission lines, resulting in low VSWR and low insertion loss.
- Raised metal grounding ring: 360° metal-to-metal contact can be realized, which enhances the grounding performance and stability of the connector.
- Temperature adaptability: it can work normally under the ambient temperature from -55℃ to +125℃, adapting to various harsh working environments.
Application:
- Test and Measurement Equipment:
- Network analyzer: network analyzer is used to measure RF components and systems amplitude frequency characteristics, phase frequency characteristics and other parameters of the important instruments. k2.92 mm connector can be used to connect the network analyzer test port and the device under test, its high frequency characteristics and good matching performance to ensure the accuracy and reliability of the test results. When testing high-frequency circuits, filters, amplifiers and other RF devices, the K2.92 mm connector can provide a stable connection to ensure that the test signal is transmitted without interference.
- Spectrum Analyzers: Spectrum analyzers are used to analyze the frequency components and power distribution of signals. In RF and microwave band testing, the K2.92 mm connector can introduce the signal to be tested into the spectrum analyzer to help engineers analyze and diagnose problems with the signal. For example, during the debugging and maintenance of wireless communication equipment, the combination of a spectrum analyzer and a K2.92 mm connector can be used to detect whether the spectrum of the signals emitted by the equipment is in accordance with the standard, and whether there are problems such as interfering signals.
- Power Meter: The power meter is used to measure the power level of RF signals. the K2.92 mm connector can be used to connect the power meter and the measured signal source, and its low insertion loss characteristics can ensure the accuracy of the measurement results. In the test of RF power amplifiers, transmitters and other equipment, the use of K2.92 mm connectors can accurately measure the output power and evaluate the performance of the equipment.
