TC-8.000MCE-T

The TC-8.000MCE-T Oscillator is a miniature, low power module designed for applications in radio frequency (RF) cellular base stations market. This type of oscillator has an adjustable split-frequency range covering 818 to 960 MHz, in 30 kHz increments. It has an external control interface and integrated temperature and power supply sensors.

The TC-8.000MCE-T Oscillator operates using common bipolar transistors to generate a harmonic oscillation signal. This signal can be frequency tuned by changing the supply voltage to the transistors. The transistors are coupled with a combiner that amplifies and separates the signal into the desired frequency range. The output of the combiner is then sent to the external impedance matching circuit to optimize the power delivered to the transmitting antenna. The frequency range of the module is adjustable from 818 to 960 MHz, with a tuning range of 30 kHz increments.

The typical operating power requirement of the TC-8.000MCE-T Oscillator is about 1.5V DC, yielding a Nyquist-optimal phase response over a -6dB frequency range of 818 to 940 MHz. The current draw is typically just over 4mA, and the module is typically mounted on the circuit board by means of solder pads.

The TC-8.000MCE-T upports the integration of extra features such as on-board temperature and power supply sensors. These sensors are connected to the external control interface, and can be used to monitor the temperature of the transistors, as well as the power delivered to the antenna. The module also supports the integration of a RF conditioning switch, which can be used to switch the output signal between two frequencies.

In summary, the TC-8.000MCE-T Oscillator is a low cost, highly efficient, miniature module designed for RF cellular base station applications. It has an adjustable frequency range of 818 to 960 MHz, in 30 kHz increments, a -6dB frequency range of 818 to 940 MHz and a typical operating power requirement of 1.5V DC. It also supports the integration of on-board temperature and power supply sensors, as well as an RF conditioning switch.
