High Q ? Insertion Loss. Filter center frequency must change to select a given channel ? tunable filter difficult to implement. Mixing has big advantage! Translate information down to a fixed (intermediate frequency) or IF. 1 GHz ? 10 MHz: 100x decrease in Q required. Don't need a tunable filter. IF. High Q channel filter.
Instead accurate matching of the amplifier stages preceding and following the mixer is one solution. Tap off the IF from the RF balun: By tapping of the IF output from the RF input, it is possible to achieve a far greater level of LO rejection - typically 20dB.
RF Mixing / Multiplication Basics. RF mixers and the process of RF mixing or multiplication used in RF technology to provide frequency conversion as well as phase comparison.

2. What is a mixer. • Frequency translation device. – Convert RF frequency to a lower IF or base bandfor easy signal processing in receivers. – Convert base band signal or IF frequency to a higher. IF or RF frequency for efficient transmission in transmitters. • Creative use of nonlinearity or time-variance. – These are usually

oscillator with a fixed amplitude sinusoid. In a down-conversion mixer, the other input port is driven by the “RF" signal, and the output is at a lower IF intermediate frequency. In an up-coversion mixer, the other input is the IF signal and the output is the RF signal. A. M. Niknejad. University of California, Berkeley. EECS 142

The hybrid junction provides a natural method by which to create the single balanced mixer as shown in Fig. 5. Additionally, two diodes are used instead of one. Key features of the single balanced mixer include: 1. Isolation (and hence frequency independence) between RF and LO ports.
