| Sumario: | The design, simulation, implementation and measurement of an analog frequency converter (up-converter) with a modular architecture is presented. A carrier of 98 MHz (center of the commercial FM band) is increased up to 2.16 GHz (Long-Term Evolution band, LTE). For the conversion, a double balanced diode passive mixer is used and a bandpass filter with coupled microstrips is implemented to attenuate the intermodulation products and unwanted signals after the conversion. This circuit is the second stage of a double conversion up-converter that raises the frequency from 10.7 MHz to 2.16 GHz, to be used in LTE applications. Results of simulations and measurements are shown. |
