The SA614AHRX is an RF Misc ICs & Modules product released by NJRC. It is a medium power mixer & amplifier for commercial and military wireless applications. This component has an excellent combination of conversion loss, linearity, and noise figure performance. It is ideal for use in communication systems with a medium power requirement. This component is also suitable for use in a wide variety of analog signal processing applications.

This device is designed as a low-voltage monolithic double-balanced mixer/amplifier with a frequency range from 500KHz to 3GHz. It has a conversion gain of 21dB with excellent harmonic suppression. It can operate at a single voltage supply of 5V and has typical 3-dB bandwidth of 3GHz. The SA614AHRX has two independent input ports, one labeled RF and one labeled IF, as well as an output port. The RF port is used for input signals from 500KHz to 3GHz while the IF port is typically used for signals from 500KHz to1GHz.

The device works by first converting the RF signal to an IF signal using a mixer process. The mixer is followed by a variable gain amplifier, typically fed back from the output stage, which improves the linearity and the noise floor of the resulting signal. The gain of the amplifier is controlled by an external DC voltage applied to a control port of the device. This enables the user to adjust the gain of the amplifier to tailor the system to the specific application.

The SA614AHRX provides excellent performance in the most demanding of applications. It has low noise figure of 1.5 dB and an IP3 of 43 dBm. It also has low insertion loss, excellent harmonic suppression, and low intermodulation distortion. It is ideal for use in satellite communication systems, VSATs, GPS, and other communication systems requiring medium power devices with superior performance.

The SA614AHRX can also be used as a broadband amplifier in a wide variety of analog signal processing applications. It is especially suitable for high linearity direct-conversion receivers requiring low noise and low intermodulation distortion. This device can also be used in devices requiring medium input power linear amplification and low noise, such as cordless phones, data modems, and closed-circuit video systems.

In conclusion, the SA614AHRX is a premium RF Misc ICs & Modules from NJRC. It is a medium power mixer & amplifier that offers excellent conversion loss, linearity, and noise figure performance for a wide variety of applications. This device is suitable for use in satellite communication systems, VSATs, GPS, and other communication systems requiring medium power devices with superior performance. It can also be used in a variety of analog signal processing applications.
