TFF1014HN/N1,115 RF/IF and RFID

RF Mixers

RF mixers are electronic devices that combine two signals and produce a signal with the frequency of the sum and difference of the frequencies of the two input signals. The TFF1014HN/N1,115 is a typical example of an RF mixer.

Application Field

The TFF1014HN/N1,115 is a wideband RF mixer designed for use in commercial and industrial applications. The device is designed to mix signals in the frequency range of 10.7 MHz to 1.7 GHz and has an operation bandwidth of 3 GHz. This makes it suitable for applications such as radio transmitters, receivers, and signal generators.

Working Principle

The TFF1014HN/N1,115 is a diode-ring mixer. This type of mixer uses four independent diodes connected in a ring configuration. The two input signals are connected to two nodes of the diode ring, and the output signal is taken from the other two nodes. The diodes are designed to allow only one signal to pass at a time. When an input signal is applied, the diode non-linearities mix the two signal components to produce the sum and difference components. As both signals are mixed, there is a conversion gain associated with the process. This makes it suitable for use in applications where a gain in the output signal is desirable.

Conclusion

The TFF1014HN/N1,115 is a wideband RF mixer designed for commercial and industrial applications. The device is based on a diode-ring mixer design, which allows it to mix two signals and produce a signal with the frequency of the sum and difference of the frequencies of the two input signals. This makes it suitable for applications such as radio transmitters, receivers, and signal generators.
