RF Mixers

RF mixers are used in radio electronics for frequency conversion. They are employed in a wide range of application fields, such as communications, instrumentation, radar, and other microwave applications. One particular type of mixer is the MAX1995ETX+T, a double balanced silicon bipolar diode mixer. This paper will cover the application field and working principle of the MAX1995ETX+T.

Application Field of the MAX1995ETX+T

The MAX1995ETX+T is targeted at applications requiring high linearity and wide dynamic range performance from as low as 100 MHz to 1.5 GHz. This frequency range is ideal for such applications as base station receivers, some interstage filters, and cellular PCS applications. The MAX1995ETX+T is also suitable for applications such as frequency mixing, data conversion, and signal processing where high linearity and wide dynamic range performance is required.

Working Principle of the MAX1995ETX+T

The MAX1995ETX+T is a double balanced mixer consisting of two unity gain amplifier stages, an IF amplifier, and two parallels diodes. When an incident RF signal is applied to the RF port of the device, the input is amplified by the unity gain amplifier stages, and the amplified signal is directed to the two parallel diodes. The diodes act as a rectifier, and the resulting rectified signal is directed to the IF amplifier. The amplified signal is then output from the IF port of the device. By performing these operations, the mixer is able to convert the input RF signal to an IF signal.

Conclusion

The MAX1995ETX+T is a double balanced silicon bipolar diode mixer. It is designed for use in application fields such as communications, instrumentation, radar, and other microwave applications. It operates over a range from 100 MHz to 1.5 GHz and is ideal for applications requiring high linearity and wide dynamic range performance. The MAX1995ETX+T operates by the incident RF signal being amplified by the unity gain amplifier stages and then directed to the two parallel diodes. The rectified signal is then directed to the IF amplifier and output from the IF port.
