RF (radio frequency) switches, which are used to control the flow of RF signals, come in a variety of form factors. One popular form factor is the HMC986A RF switch. This switch, which is based on an array of miniature MEMs (micro-electromechanical systems) relays, offers excellent performance for wireless communication applications while being highly compact in size.

The HMC986A is a low-noise broadband switch, with a maximum isolation of greater than or equal to 65dB and a typical insertion loss of 0.3dB. It has an IP3 rating of better than 50dBm, which is necessary for many successful applications. The switch can operate in the 800-3000MHz range, is capable of handling up to 24dBm and is ideal for applications such as Bluetooth, Wi-Fi, GPS and cellular base stations.

The HMC986A is a digital switch and is designed for automated control, allowing it to be used for a variety of tasks, such as antenna switching for simultaneous multiple communication systems, or for antenna and power splitting. It is highly reliable, with an operational life of more than 10 million cycles. It has a self-test feature and features integral overvoltage and reverse-voltage protection.

The HMC986A works on the basis of a micro-electromechanical system, or MEMs, which is a miniature but powerful structure composed of many tiny components, including a metal or silicon structure, springs, electrical contacts and sensors. These components are connected together to allow them to achieve levels of accuracy and reliability that are not possible with other types of relays. The MEMs device is actuated by an electrostatic force, meaning it is triggered by applied electric fields, thereby eliminating the need for a separate power supply.

The HMC986A is controlled by an embedded controller, which provides built-in digital and analog interfaces. This is used to integrate the HMC986A into more complex circuits and systems. The controller can be easily rewritten and updated in order to adapt the switch to new or changing requirements.

The HMC986A is a popular and reliable choice for a wide variety of RF applications, and is particularly suited for wireless communication and antenna switching. Its combination of small size and high performance make it ideal for applications where space is limited, but reliability and accuracy are essential.
