Hittite announces the release of eight MMIC voltage controlled oscillators (VCOs) that cover wireless infrastructure, test equipment, microwave radio and military applications between 2 and 6.8 GHz. The MMIC VCOs are fabricated on a production qualified process and integrate the resonator structure, negative resistance circuitry, tuning varactor and output buffer amplifier, thus requiring no external components. Output signals are delivered at power levels between +3.5 to +5.0 dBm typical from model to model. Both the 10 kHz and 100 kHz Single sideband (SSB) phase noise performance has levels at 89 dBc/Hz and 𤩣 dBc/Hz respectively. The frequency drift rate of the MMIC VCO products range between 0.25 to 0.8 MHz/°C from model to model.
