GS101
24GHz K-Band Stereo Microwave Module
Product Description
24GHz-ISM-Band
Direction recognition
LCO-oscillator with low current consumption
15dBm EIRP power
Beam aperture 80°/34°
GS101 is a stereo K-Band transceiver with an 8-patch Doppler module. Its typical applications include movement sensors for lighting, access control, gate control, automatic door control, security, and device activation. In building automation, this module may serve as an alternative to infrared PIR or AIR systems due to its outstanding performance, movement direction identification, and cost-effectiveness ratio.
Applications
Lighting Control
Access/Gate Control
Security
Motion sensor switch
Intelligent Surveillance Device Activation

Sensitivity and Maximum Range
The values indicated here are intended to give you a 'feeling' of the attainable detection range with this
module. It is not possible to define an exact RCS (radar cross section) value of real objects because
reflectivity depends on many parameters.
Using this formula, you get an indicative detection range of
- 12 meters for a moving person.
- > 31 meters for a moving car
Please note, that range values also highly depend on the performance of signal processing,
environment conditions (i.e. rain, fog), housing of the module and other factors.
For simple detection purposes (security applications e.g.) without the need of speed measurements,
range may be enhanced by further reducing the IF bandwidth. With 250Hz bandwidth and a simple
comparator, we get already a 25m detection range.
