RF Mixers

Mixers are a type of frequency-conversion device which holds an important role in many radio frequency applications. The TFF1018HN/N1,135 is a parametric RF mixer that operating in the 1GHz frequency range hence widening its application field. It is widely used for wireless data transmission, frequency conversion as well as divider and multiplier applications in various fields.

Working Principle

The TFF1018HN/N1,135 operates on the working principle of the heterodyne effect. The device consists of two inputs – local oscillator (LO) and radio frequency (RF) – and two outputs – sum (S) and difference (D). Oscillator signals of the same frequencies from opposite directions are received at the LO and RF ports respectively and the mixer combines the two signals which will then produce two frequencies – the sum frequency (RF + LO) and the difference frequency (RF – LO).The sum frequency is the output S port, while the difference frequency is the output at D port.

Performance Characteristics

The typical performance of TFF1018HN/N1,135 are:

• Mixer conversion loss is no more than 17dB @ 1.0GHz
• Frequency range of 400MHz to 4GHz on LO port
• Input and output frequency-dependent loss of 6dB
• Maximum input-drive power of 17dBm

Applications

Suggested applications of TFF1018HN/N1,135 are:

• Modulation and demodulation
• Wireless communications
• Frequency synthesis
