HMC547LP3TR

RF switches are a type of necessarily electronic component designed to switch an RF signal on or off. The HMC547LP3TR is a low noise, high power, integrated SPDT switch fabricated with an InGaP Heterojunction Bipolar Technology (HBT) process. This switch is designed for use in transmit and receive applications from DC to 6.0 GHz. It operates from a single positive power supply of +3.0 VDC. Having a low insertion loss at high frequencies, the HMC547LP3TR can handle up to 27 dBm of input power, making it ideal for a wide range of applications.

Application Field of HMC547LP3TR

The HMC547LP3TR provides a low insertion loss and high linearity, making it a great choice for applications requiring the most efficient RF signal routing. Therefore, this device is commonly used in telecom and wireless communication systems, such as cellular base stations, CATV optical network units, microwave radios, WLAN transceivers, and digital radio systems. In satellite communications, this switch is featured in applications as high as Ku-band. Additionally, the HMC547LP3TR is popular in military and aerospace applications that need precise and reliable switching and routing of signal paths.

Working Principle of HMC547LP3TR

A single +3V power supply voltage is provided to the HMC547LP3TR for operation. This device contains two RF signal paths; each path containing five RF switching components (two dual-gate MOSFETs and one single-pole, double-throw (SPDT) switch). A logic input is used to control the state of the RF paths; when the logic is set to one level, the first RF path is activated and the second is disabled, when the logic is set to the other level, the first RF path is disabled and the second is activated. By controlling the state of the RF paths, the HMC547LP3TR can be used to connect or disconnect various portions of a signal path in a controlled, precise fashion. This switch also has a forty-pin package, making it easy to integrate with various other RF components.

Conclusion

The HMC547LP3TR is a high performance RF switch that provides low-noise and high power handling capability up to 27 dBm. It is capable of operating from DC to 6.0 GHz and is powered by a single +3 VDC power supply. It is offered in a forty-pin package, making it easy to integrate with other RF components. This device is suitable for a wide range of applications such as telecom and wireless communication systems, microwave radios, digital radio systems, and military and aerospace applications.
