The HMC728LC3CTR-R5 is a special purpose analog switch device that belongs to the interface-analog switch category. This device is a low-noise analog signal switch, which offers high linearity performance, low insertion loss and low crosstalk levels. It is ideal for application in communications, industrial, automotive and measurement instruments.

The HMC728LC3CTR-R5 provides a robust solution of low-cost, low-noise, high-switching performance. It offers ultra-broadband performance from DC to 20GHz with excellent switching characteristics, such as low insertion loss, high isolation and low crosstalk. Its low-noise, low-distortion design make it ideal for applications that require high linearity like signal routing and frequency translation in cellular base stations and measurement instruments.

The HMC728LC3CTR-R5 operates from a single +12V/+24V DC bias supply, which makes it suitable for applications in space-constrained designs. It is also equipped with a maximum switching speed of 10ns and a maximum on resistance of 0.5Ω making it suitable for a wide range of applications. Additionally, it features a positive logic control interface which allows digital control of the device with a logic low level.

The working principle behind the HMC728LC3CTR-R5 is based on a dual-JFET switch. It consists of two N-channel JFETs connected in parallel and arranged in series between the two input/output pins. An on-off voltage is applied to the gate of one JFET, thereby turning it on and off. The other JFET is maintained off so that the on-off voltage is not applied to it. Hence, the device can be switched on and off depending on the logic level applied to the gate. When logic high bias is applied, the device is in an on state, allowing signals to flow between the two pins.

The HMC728LC3CTR-R5 is an ideal solution for applications requiring low-noise, low-distortion, low-cost and high-switching performance. Its robust design and low-power consumption make it suitable for space-constrained designs. The device provides exceptional linearity performance and a positive logic control interface for ease of digital control. It is a very reliable device, making it suitable for use in communications, industrial, automotive and measurement instruments.
