Microwave Receiver

Detect and hear microwave signal changes in real time across a wide field

The Microwave Receiver uses a plate antenna to detect the 10 GHz signal from the Microwave Transmitter. The plate design captures signal across a wide area, so small positional shifts during setup and student handling don't kill the signal mid-demo. Amplitude changes feed directly to an internal loudspeaker, making wave behavior audible to the entire class the moment conditions change.

A front-panel sensitivity control adjusts the gain for different experiment distances and room sizes. Four millimeter output sockets let you connect a multimeter or oscilloscope for basic amplitude readings when a qualitative demo isn't enough.

Why Teachers Love It

• Wide Detection Area Tolerates Student Handling: the plate antenna picks up signal over a broad zone, so reflectors and obstacles can be moved in and out of the beam during a demo without the class losing the signal because of minor misalignment.

• Loudspeaker Output for Whole-Class Demos: amplitude changes are audible the moment a reflector, shielding material, or polarizer enters the beam path, so students in the back of the room get the same real-time feedback as those at the bench.

• One Knob Covers All Room Sizes: the sensitivity control handles close-range benchtop work and longer-distance classroom setups with no component changes, cutting down setup time between experiments.
