General Applied Engineering GA3120 Dual Directional Coupler

Used with a little cosmetic ware, GA3120 Dual Directional Coupler  
 
The GA3102 and GA3104 Dual Directional Waveguide Couplers are part of the WaveProbe™ family of waveguide couplers that offer high performance microwave power monitoring in a small package. The WaveProbe™ secret to accurate and reliable waveguide power measurement is in the design of the probe itself. Utilizing a common loop type design, the probe terminates in a proprietary RF resistor configuration that provides excellent directivity and a stable coupling factor. Model GA3104 features the popular WR284 Q-D (quickdisconnect) round flange that can be used with a quick-release clamp (Model GA8410) for waveguide connections.
