HMC-C071

RF Switches are an important component of various radio frequency systems. The HMC-C071 RF Switch is designed for use in applications requiring high linearity and low insertion loss. This Switch is suitable for use in high dynamic range systems that require fast switching times.

Application Field of HMC-C071

The HMC-C071 Switch is suitable for use as a switch-matrix switch in a variety of applications. These include multiple antenna systems for automotive, cell phone, and mobile radio applications. It is also suitable for use in microwave communication systems for demanding applications such as base station infrastructure, high data rate radio-over-fiber systems, and avionics. Additionally, it is suitable for use in RADAR and satellite systems.

Working Principle of HMC-C071

The HMC-C071 Switch works according to the PIN diode attenuator principle. It uses an insulation-displacement (IDC) contact technology to connect or disconnect the RF paths. The PIN diode is used to attenuate the input signal in the off-state and enable a low insertion loss in the on-state. The PIN diode attenuates the signal in the off-state to prevent signal leakage. This reduces the overall system noise floor and allows for higher sensitivity in the receiving chain.

The HMC-C071 Switch is controlled using a logic control voltage. This allows the switch to be switched on or off quickly. The logic control voltage also enables the switch to change states in less than 5 microseconds, which is necessary for many of the applications in which this switch can be used.

The HMC-C071 Switch has an insertion loss of less than 0.3 dB in the on-state, which allows it to be used in systems with higher power requirements. The Switch also features a low return loss, meaning the reflected signal is low, even when used in high power systems. This reduces the risk of signal distortion and ensures the accuracy of the transmitted signal.

The HMC-C071 Switch is also temperature stable, meaning the switch\'s switching characteristics remain linear over temperature ranges from -40°C to +85°C. The Switch is also rated to withstand transient voltages up to 18 V. This ensures reliable operation in demanding environments.
