drew microwave designers to booth 2724 at this week's IMS exhibition with information about its new lines of dual-output voltage-controlled oscillators (VCOs) for applications through 15.5 GHz. The monolithic-microwave-integrated-circuit (MMIC) oscillators are based on InGaP/GaAs heterojunction-bipolar-transistor (HBT) technology and supplied in low-loss 32-lead QFN packages measuring just 5 x 5 mm. As an example, model EWV0801YF has a fundamental-frequency range from 7.3 to 8.3 GHz with typically +12 dBm output power and a divided frequency range of 3.65 to 4.15 GHz with typically +6 dBm output power. It tunes via control voltages of 2 to 13 V and supply current of typically 275 mA. The phase noise is -112 dBc/Hz offset 100 kHz from the carrier, while subharmonic levels are typically -40 dBc and second-harmonic levels typically -30 dBc. The company offers a variety of the surface-mount VCOs, typically in approximate 1-GHz tuning bands from 7.3 to 15.5 GHz.
