Conversion gain and intermodulation performance of a GaAs HBT 50-950 MHz upconvertor

摘要

The authors report the measured performance of a single ended GaAs heterojunction bipolar transistor (HBT) upconverting mixer from 50 to 950 MHz, showing a conversion gain of 19.4 dB and output intermodulation intercept point (OIP/sub 3/) of +20.5 dBm with local oscillator drive power of 0 dBm. The measured results demonstrate the suitability of the HBT for use in low power consumption upconvertor circuits.
