HMC349 RF Switch Board

Order the HMC349 RF Switch Board for Precise Signal Control!

HMC349 RF Switch Board is a turnkey solution for managing high-frequency signals. It is based on the HMC349 integrated circuit from Analog Devices. The board allows you to switch RF paths in your system. You can easily control antennas or signal sources. It is an essential component for complex RF devices and test benches.

This board performs the function of an electronic switch. It directs the high-frequency signal along one of several possible paths. Control is carried out using low-voltage digital signals. You get the ability to quickly and accurately change the circuit configuration. This is an indispensable tool for developing and testing radio electronics.

• High switching speed between channels.

• Wide operating frequency range up to several gigahertz.

• Low insertion loss and high channel isolation.

• Easy to control via TTL/CMOS logic levels.

• Ready to use board with connectors and stabilizer.

How does this high frequency switch work?

The board is based on the HMC349 integrated circuit. This is a monolithic SP4T (single-input, four-output) CMOS switch. When a certain combination of voltages is supplied to the control inputs. The internal electronics complete the path between the common input and one of the outputs. The signal passes through with minimal distortion and loss.

The key parameter is the high-frequency response. The board is designed to operate efficiently over a wide range. It introduces minimal loss into the signal and provides good isolation of unused outputs. This allows for clean and predictable paths. Control is carried out using simple binary codes.

Technical characteristics and applications

The board has specific technical parameters. Operating frequency range from DC to 6 GHz. Insertion loss at 1 GHz is about 1 dB. Isolation between channels is more than 40 dB. The switching speed is about 10 nanoseconds. Power requires one positive voltage from +3V to +5V. Control inputs are compatible with CMOS/TTL levels.

The functionality of the board allows you to implement various scenarios. Switching between multiple antennas in a Diversity system. Selecting a signal source for the analyzer or receiver. Creation of programmable attenuators or phase shifters. Use as part of switching matrices for automatic measurements. Any application where an RF signal needs to be controlled benefits from this solution.

This board is especially useful for developers and researchers. It saves time on creating your own switch breadboard. You get a ready-made, debugged and predictable device. This speeds up the prototyping and testing of new devices. The board can also be used in small series end products.

Installation and use of the board is intuitive. Signal sources and receivers are connected to SMA connectors. +5V or +3.3V power is supplied to the corresponding contact. Control signals are supplied to inputs SEL0 and SEL1. The logic level determines which output is active. The board does not require additional configuration or calibration.

The quality of the board's manufacturing ensures the stability of the parameters. High frequency PCB with precise transmission lines is used. All SMA connectors have high-quality soldering and collet mounting. A voltage stabilizer is installed on the board to provide clean power to the microcircuit. The markings of contacts and elements are clear and understandable.
