How to Select a Proper Connector for Your LadyBug Power Sensors
LadyBug Technologies is one of the leading manufacturers of NIST traceable power sensors. These power sensors have gained immense popularity in recent years, owing to their special features such as the patented No Zero No Cal feature, industry-leading accuracy, and availability in a broad range of frequencies. Like any other RF device, power sensors need to be connected properly to produce the desired results. This RF connection must be made using the proper connector. This post discusses the various types of connectors provided by LadyBug for its power sensors and recommendations for use.
Types of connectors for Microwave Power Sensors
At LadyBug, we provide the following types of standard and optional connectors:
- Type N Connectors: These durable medium-sized RF connectors are designed for signals up to 18 GHz. Available in male and female types, Type-N connectors find regular applications in low-frequency microwave systems such as spectrum analyzers.
- 3.5mm: The connector has the upper operational frequency of 26.5 GHz, and is mode free to 34 GHz. This connector serves as a test connector for SMA capable devices. The SMA – 3.5mm interface is proven to offer better results than an SMA-SMA interface. This connector features a thick outer conductor shoulder and an air dielectric mating surface. It maintains excellent electrical and mechanical integrity through many mating cycles. (Some SMA male connectors may damage a female 3.5 mm, however the SMA connectors on LadyBug power sensors will not damage 3.5mm female connectors.)
- 2.92mm: The connector mates with 3.5mm and SMA connectors, and is designed for operational frequencies up to 40 GHz. This connector could also be referred to as a K-type connector. The 2.92mm connectors are excellent for high-frequency and T&M applications. (Some SMA male connectors may damage a female 2.92 mm, however LadyBug SMA connectors will not damage 2.92mm female connectors.)
- SMA: SMA connectors are one of the most used RF connectors in general use today. LadyBug SMA connectors are special high performance connectors with performance and service life similar to 3.5mm connectors. These connector is rated for frequencies up to 26.5 GHz and has a solid dielectric interface. It is compact in size, durable, and available in high-frequency variants. It can be mated with various types of connectors and unlike other SMA connectors, LadyBug’s SMA will not damage 3.5mm or 2.92mm connectors.
Recommended Connectors for Power Sensor Models at LadyBug
When using microwave and RF test instruments, adaptors add uncertainty to the measurement. Ideally, the sensor is connected directly to the DUT (Device Under Test). Use our standard recommend connectors or purchasing an optional connector that mates directly with your DUT.
LadyBug provides three types of power sensors for RF and microwave markets— True RMS Sensors in 9 kHz to 40 GHz, Peak, Pulse, and Averaging sensors in 10 MHz to 20 GHz frequencies, and Wideband Pulse Profiling Sensors in 50 MHz to 20 GHz frequencies.
The experts at LadyBug recommend the following types of standard connectors for sensors:
- Type-N male connectors for sensors with a maximum frequency of 18 GHz.
- 3.5mm male is a standard connector for sensors with a maximum frequency of 26.5 GHz. These sensors are also compatible with SMA.
- 2.92mm male is a standard connector for sensors up to 40 GHz. These connectors are also compatible with 3.5mm & SMA connector types.
For any queries on the right connectors for True RMS, Peak, Pulse, and Averaging, as well as Wideband Pulse Profiling Sensors, you can always get in touch with the experts at LadyBug, who come with a combined industry of 60+ years in RF & microwave testing and measurement services.
