Zusammenfassung:Two types of monolithic multipliers have been developed using current AlGaAs HBT (heterojunction bipolar transistor) technology. Both circuits have an extended input frequency range of 10 MHz to 1.0 GHz. Preliminary wafer probe measurements indicate that the even-order multiplier achieves 45 dB of fundamental rejection and 22 dB conversion loss at 2.5 GHz (10th harmonic), consuming 175 mW. The odd-order multiplier exhibited 21 dB of conversion loss at 10 GHz (10th harmonic) and 35 dB at 21 GHz (21st harmonic), dissipating 315 mW. These circuits offer significant improvement in bandwidth and output power as well as lower implementation cost compared to existing diode-based MIC (microwave integrated circuit) or MMIC (monolithic microwave integrated circuit) MESFET frequency multipliers.< >
