Part details & applications

The ADH732S is a wideband, MMIC, Hybrid Voltage Controlled Oscillator which incorporates the resonator, negative resistance device, and varactor diodes. Output power and phase noise performance are excellent over temperature due to the oscillator's monolithic construction. The Vtune port accepts an analog tuning voltage from 0 to +23 V. The ADH732S Hybrid VCO operates from a single +5V supply, consumes only 62 mA of current, and is housed in a 12-Lead hermetic package. This wideband VCO uniquely combines the attributes of ultra small size, low phase noise, low power consumption, and wide tuning range.

Applications

Point-to-Point/Multi-Point Radios
Satellite Communications (SATCOM)
Controls
Military & Space
