Spectrum Control offers a complete line of Digitally Tuned Oscillators (DTOs). These custom designed DTOs consist of a select number of sub-band VCOs covering customer specific frequency ranges between 2 GHz and 18 GHz.
APITech offers a complete line of Digitally Tuned Oscillators (DTOs). These custom designed DTOs consist of a select number of sub-band VCOs covering customer specific frequency ranges between 2 GHz and 18 GHz.
The sub-band RF outputs are selectively switched to a common RF output port. Sufficient sub-band overlap insures full band coverage for these DTOs.
Digital tuning is via a 16 bit, parallel input word. Several bits are used for selecting the desired sub-band and 12 to 14 bits are used for frequency tuning.
Silicon semiconductors are used to provide the best possible phase noise and post tuning drift performance.
APITech offers standard features including: fast settling time (< 1 msec), wide frequency range (2-18 GHz), low post tuning drift (<4 MHz @ 1 msec), low spurious output (< -60 dBc), harmonics (-25 dBc max), as well as excellent phase noise performance (<-65 dBc/Hz @ 100 kHz).
Additional features include: low residual FM (<-20 dBc @ 100 kHz), RF output power (+10 to +16 dBm), high reliability for military applications, and fully-customizable output connectors.
APITech also supports the following optional DTO features: power output status indicator, phase locked module with phase lock indicator, internal heater for frequency stability over temperature, analog FM input.
Hybrid MIC Technology
Hybrid MIC technology reduces overall package size and helps ensure overall system reliability. Fast settling time and excellent spectral purity make APITech DTOs ideal for simulators and other EW applications.
