Abstract
The critical part of a broad-band TV tuner, i.e., the upcon-verter was fabricated with simple GaAs IC\´s. The results obtained were: 1) "Pure" frequency spectrum due to double balanced mixer configuration. 2) Constant conversion gain of 12 ± 2 dB over the entire TV band (50-900 MHz). 3) Good linearity for large signals: Suppression of third-order intermodulation >40 dB for typical bias. 4) Low noise figure (typically 8 dB). These data demonstrate the feasibility of a monolithically integrated single-range TV tuner on GaAs.
