Figure 2. Reference module with SMA Such a module also makes it possible to take return loss and impedance measurements on a network analyzer looking into the matching network following the radio RF ...

A few years back, [Roman Black] experimented with the cheap RF modules you can find on auction sites and from surplus electronics vendors for only a few dollars, and wrote up his findings.

Targeted for the smart home, this design leverages two PIC MCUs that use a wireless RF transmitter/receiver to control up to six relays and monitor two analog signals.

What he ended up with is an RF base station that can learn to take commands from different remote devices. The main components include the solid state relay at the bottom of the image.

These fully integrated modules are suitable for use in telecommunications, test instrumentation, electronic warfare, aerospace, and radar applications. ADI can also perform additional levels of ...

For power, the RF modules would use a fixed or removable rechargeable battery, such as a lithium-ion battery, disposable alkaline battery, or any other portable power source, including kinetic ...

Murata’s millimeter-wave RF modules use an independently developed LTCC* that realizes stable communications quality in the millimeter-wave band and features both high heat and moisture resistance.

In this design idea, you will learn how to interface two PIC microcontrollers using a wireless 433-MHz RF transmitter/receiver pair to control up to six relays and monitor two analog signals. The ...
