Oscillators

TD-70.000MCD-T is a high frequency oscillator designed for applications requiring a very wide tuning range and an adjustable phase noise performance. The oscillator consists of a thin film resistor suspended in a dielectric with an integrated thin film varactor. The resonator is embedded in a coplanar waveguide circuit board technology.It is an excellent choice for applications such as tunable voltage controlled oscillators (VCOs) and high performance phase locked loops (PLLs) where a low noise signal is needed.The TD-70.000MCD-T consists of two components, the main oscillator core and an auxiliary tuning element. The core contains the thin film resistors, the integrated varactor and the resonator which is responsible for producing the frequency signal. The auxiliary element is responsible for controlling the tuning range of the oscillator, allowing the user to adjust the frequency signal within certain limits. The maximum frequency tuning range is determined by the varactor parameters.The output of the TD-70.000MCD-T is a square wave signal with a variable frequency. The frequency range is determined by the changing voltage to the varactor, resulting in an adjustable frequency span from DC to a maximum of 70GHz.The TD-70.000MCD-T can also be used as a fast transient oscillator with a wide frequency tuning range and low phase noise performance. This makes it ideal for use in PLL circuits. The frequency response rate of the oscillator is very high, allowing instant frequency changes for short duration pulses. This is useful for recording events or controlling switching frequencies. The output of the oscillator is also well-regulated and is immune to power supply variations.In terms of power consumption, the TD-70.000MCD-T is very efficient. It requires a single supply voltage and operational current is less than 300 mA. The oscillator also includes a static and dynamic protection circuit which helps protect the oscillator from any sudden changes in power supply. This makes the oscillator suitable for long-term operation when using standard CMOS power supplies.Overall, the TD-70.000MCD-T is a highly versatile oscillator with a wide tuning range and low phase noise performance. It is suitable for a variety of applications such as VCOs and PLLs, and its high frequency response and low power consumption make it an ideal choice for short duration pulses or fast transient oscillators.
